Support Statement


If you are reading this, you have either purchased a Linkswell T-style radio from ADC Mobile or are contemplating the purchase. If you have already purchased – THANK YOU! We will do our best to surpass your expectations for support after the sale.

If you are contemplating the purchase, we are confident you will find that ADC Mobile knows more about the Linkswell T-Style systems than anyone and we will do our very best to support you in that purchase. Due to the fact that we are part of the Linkswell Engineering & Beta Team, we have access that very few other dealers have with the factory engineering and support staffs.

We know that there are many places you can find these products, but there are some VERY IMPORTANT differences in the dealers you may purchase from. We have over 120 YEARS in professional car audio installation experience on our staff, which gives us a dramatically wider “field of view” of potential issues that may affect your vehicle and your installation, and we have tried to distill those experiences into this guide. 

IMPORTANT NOTE ON FACTORY SUPPORT: Linkswell limits the support they provide to their FACTORY AUTHORIZED DEALERS ONLY. They do not work directly with the purchaser, so if you call the factory, they will route you back to your dealer for support – this means that with ADC Mobile you will get the benefit of all of our experience with the product – with other dealers, not so much…

On the front page of the Linkswell website, there is a notice regarding purchases made on Amazon or EBay:

Technical Support & Warranty Disclaimer

Linkswell believes that due to the technical nature of our products, our products are best represented and consumers are best served by our team of factory trained and supported dealers. We highly recommend purchasing our products from one of the factory authorized dealers found here: .

Due to the nature of online shopping platforms like Amazon and eBay, consumers of our products cannot be adequately supported on those platforms and accordingly, we limit support for products purchased there.


We always advise our customers to do what is right for them, and we realize that we may not always be the best option for every customer, but before you purchase Linkswell product on Amazon or EBay, think long and hard about the lack of support you will experience on what is a VERY technical and expensive system upgrade. With our competitive pricing (tax-free if outside WA state), free shipping and unlimited phone & email tech support with real installers, we feel that purchasing from ADC Mobile is the smartest place to spend your money on your new Linkswell T-Style upgrade! :- )

Firmware Updating

Keeping your unit upgraded to the latest firmware is CRITICAL for smooth and trouble-free operation!

All Linkswell radios run on custom firmware that incorporate the additional features required to interact with the vehicle and with the devices that attach to it.  It is important that you check occasionally for updates and apply any updates that are found.

If we have to help you troubleshoot problems, the FIRST thing we will ask is whether the unit is running the latest firmware.  With the constant flow of updates for bug fixes and feature improvements, it is vital that you try updating your unit to the latest available firmware BFORE we help you troubleshoot any problems you may have. A majority of issues can now be fixed with a simple firmware upgrade, and both ADC Mobile & Linkswell will require the latest firmware be installed prior to undergoing extended troubleshooting or warranty service.

All units sold by ADC Mobile are updated to the latest version available at the time our units were shipped from the factory, and all are currently running at least APP version 4.4, which allows over-the-air updating via Wi-Fi.

NOTE: If your GEN4 unit is not currently updated to at least APP version 4.4, it would be beneficial for you to update as soon as possible. All major firmware updates can be downloaded from the Linkswell website. (NOTE: GEN 1/2/3 radios are not capable of upgrading to the APP 4.4 firmware)

Version 4.4 adds many bug fixes and new features, including new settings menus, more settings options, additional menu bars and the ability to customize them, full-time HVAC controls in the bottom menu bar, and it also allows all future updates to be done over-the-air (OTA) via wi-fi. 

  • I have a GEN4 with the old firmware with icons down the left side on the “Settings” page – how do I update to the latest firmware (APP 4.4+) that allows OTA updates?

    • Download the latest APP file (the one with the highest number) from the Dropbox link here.
    • Format a USB drive to be sure that it is empty, then open the .zip file you downloaded and copy the one file inside titled “” to the root of the USB.
    • Verify that there is only one file on the drive  – “” – and that it is not inside a folder.
    • Take the USB to the vehicle, turn the ignition on and allow the system to boot up.
    • Disconnect all other USB devices connected to the radio including phone, DVRCAM, etc.
    • Once the unit is booted up, plug the USB drive directly into one of the USB inputs.
    • The system should recognize the update file and pop up an alert asking if you want to run the update.
    • Press yes and allow the update to run.
    • Once the update is finished, you should see some text on screen to “Unplug the USB Disk.” Unplug the USB stick, and allow the system to reboot.
    • Allow the system to reboot completely, then go to “Settings” – you should see a different layout than you had before.
    • See the next section to proceed with over-the-air updates.
  • My system is updated to APP 4.4 or higher. How do I update my system to the latest firmware?

    • When connected to a home or office Wi-Fi network, click the “SETTINGS>SYSTEM>UPGRADE” tab on the radio to check for updates. If it finds an update, it will ask you to install it. It would be beneficial to check for updates at least every 30-45 days.
  • When I try to update firmware, I get “config file not found” error

    • This failure may be related to using a hotspot connection. Do not try to do updates when connected to a hotspot if at all possible. Connect to a home or office Wi-Fi network that is capable of high-speed connection, as the APP update is almost 1GB in size and will take FOREVER on a standard hotspot connection.
    • Alternatively, this error can be seen if the factory update server is down or in maintenance mode.
  • I’ve been instructed to update the CANBOX – how do I do this?

    • NOTE: Unless instructed, it is not normally advised to do CANBOX updates, as these will be be vehicle and problem-specific updates to fix very specific issues
    • If you are instructed to do a CANBOX update, follow the instructions below:
  • I’ve been instructed to do a complete reinstallation of the factory files – how do I do this?

    • Very rarely, we may recommend doing a complete reinstallation of the operating files on the unit to help troubleshoot problems. NOTE: This is normally used as a last-ditch effort to solve specific issues and will not normally be recommended for minor problems. DO NOT DO THIS UPDATE UNLESS INSTRUCTED TO!
    • If we do recommend this process, please follow this guide to rebuild those operating files:

NOTE: After updating firmware, if your camera screen is very dark, put the vehicle in reverse, then tap the top left corner of the bar at the top of the screen to bring up the picture adjustment menu – choose “Default” to restore image settings.

We’ve had a ton of experience with the T-Style radios and have gathered our knowledge together in this FAQ that hopefully will answer a lot of your questions regarding the features, operation, installation and troubleshooting of the system. We highly recommend reading through this whole section both before your purchase and prior to installation so you can gain a better understanding of the capabilities of the unit, the idiosyncrasies of the various installations and some tips and tricks that will help your install and setup of the system go much smoother.

We will be adding to this section as time goes on, and are happy to take feedback from owners in order to make this FAQ as definitieve as possible. Feel free to contact us with your feedback on our Contact Form.

  • Will the system work on my truck?

    • The Tundra 12.1″ T-Style radio works on:
      • 2014-2021 Toyota Tundra w/Base or JBL amplified audio systems
  • Will I need to purchase any other parts to install a vehicle specific T-Style into my car?

    • No. Our system comes 100% complete with everything needed for a standard installation.
    • All parts come with the system for vehicles equipped with the JBL system or the standard audio system. 
  • Will the T-Style system make my manual climate controls into the dual and or Automatic controls?

    • No.  The system will turn your manual controls into touch screen controls but it will not add the functions of the Automatic temp control or dual climate control.
  • Will the factory remote start still work with the T-Style radio?

    • Yes.  The system will activate the climate control in remote start.  It is only able currently to support the “last position” setting and not the auto setting.
  • I live in Minnesota/Arizona – Are the screens designed to work in extreme environments?

    • Yes. The GEN4 screens are tested to perform from -20 degrees Fahrenheit to +170 degrees Fahrenheit. We have never seen a screen fail due to environmental issues
    • Here’s a video showing the cold weather testing the screens go through:
  • Can I keep the factory satellite radio tuner with the T-Style radio?

    • No.  The factory satellite tuner contained in the factory radio and is removed when installing the T-Style radio.
  • I can’t lose XM! What are my options to keep it?

  • Making my phone into a hotspot is a pain – are there other ways to add wi-fi if my truck did not come with it?

    • Yes. Many service providers have add-on hotspots that can be added to your vehicle simply by plugging an OBD adapter into your OBD port on the truck. For instance, AT&T offers a vehicle hotspot for $80 (or $4 per mo. on contract) and Unlimited Data for $30 per month
  • I don’t want to buy another hotspot device – can my phone act as a hotspot?

    • Generally, yes. However, this will be completely dependent on your device, and since the radio’s wi-fi connection will only work on 2.4G wi-fi systems, make sure your device is capable of outputting a 2.4G signal.
  • Turning on the hotspot on my phone is a pain – can this be automated?

    • Yes. Using apps like Tasker or IFTTT can allow you to automate the process of turning on your hotspot when you leave your house or, even more precisely, when you connect to the Bluetooth system on your T-style radio.
  • Will my factory camera still work?

    • Yes. if your radio currently displays the camera in the factory screen, it will have an adapter to display it in the new radio.
    • NOTE: We can only retain the tailgate handle camera. We can not retain the factory 3rd brake light camera.
  • Can I add an aftermarket camera to the T-Style radio?

    • Yes.  The system comes with 3 dedicated camera inputs, front, right and rear.
      • If your truck does not have a factory rear camera, one can be added and will trigger by default in reverse.
      • The right turn signal input is triggered from the right turn signal. The front camera input is accessible manually.
      • All camera inputs will need to be turned on in the Settings Menu in order to be used.
  • Can I add a third brakelight or trailer camera to the system as an add-on to the factory rear camera?

    • Yes.  Although the “FRONT CAMERA” input is primarily designed for use with a front-facing camera, since it is manually operated via the touchscreen, it can be used for any camera view.
      • If your truck does not have a factory rear camera, one can be added and will trigger by default in reverse.
      • The right turn signal input is triggered from the right turn signal.
      • The front camera input is only accessible manually.
      • All camera inputs will need to be turned on in the Settings Menu in order to be used.
  • Will my factory Steering Wheel Controls work?

    • Yes.  It will retain the all the functions of the steering wheel controls EXCEPT the voice control button due to the system not having any voice control functions
  • I use voice control for everything! How can I get it back?

    • If you use the PhoneLink app for Car Play or Android Auto, those apps will support full voice command (Siri and Google Assistant) just as they do on the phone.
  • Will I need to purchase any other parts to install this T-Style radio into my car?

    • No. The system comes 100% complete with everything needed for a standard installation in factory-amplified or non-amplified systems.
  • Does the T-Style Radio retain the factory Bluetooth microphone?

    • No.  Bluetooth functions require the use of the supplied microphone.
  • Where is the best place to mount the supplied microphone?

    • We ALWAYS recommend clipping the mic to the forward edge of the headliner in the center of the truck in front of the rear view mirror. Extensive testing has proven this to be the most effective location for hands-free call quality due to the fact that the headliner is specifically designed to quiet the interior and soak up vibrations from the road.
    • You may also consider zip-tying it to the harness that feeds the factory mirror.
    • DO NOT mount the microphone to any hard plastic surfaces if at all possible, as any vibration from these panels will transmitted directly into the mic, affecting sound quality.
  • How many USB inputs does the T-Style System have?

    • GEN 4 Systems come with 3 USB inputs.  The factory USB input(s) are retained and there are two additional USB’s – one is for PhoneLink (CarPlay) and one for general use/universal input.
  • What can I use the USB’s for?

    • Music & Video Play back.  The T-Style systems supports the major audio and video formats.
      • Audio: MP1, MP2, MP3, APE, WMA, WAV, OGG, OGA, FLAC, ACC, M4A
      • Video: MPG, TS, DAT, VOB, MP4, MOV, 3GP, AVI, MKV, TS, FLV, RMVB,RM, WEB, WMA, ASF
    • Data transfer.  You use the USB inputs to run firmware updates as well you can use them to download music/video files or 3rd party Android applications.
    • PhoneLink System.  See following question for more info on the PhoneLink System.
  • Can I use a mouse/keyboard on the T-style radio?

    • Yes.  Since the Android tablet that runs the system has USB inputs, any USB keyboard or mouse should work, including wireless devices that use USB receivers.
  • Will the T-Style Radios work with an iPhone?

    • Yes.  The system will work with both Android and Apple phones.  You can connect either through Bluetooth to do hands-free calling and music streaming.  You can also use the white “PhoneLink” USB dongle that plugs into one of the USB inputs and activates the PhoneLink system giving you onscreen access and control to you phones text messages, music, navigation and select applications, (ie. Spotify, Pandora, SiriusXM, Waze, etc.)
  • What navigation system does the radio come with?

    • The system comes with Google Maps already installed, but any navigation app you can download from the Google Play Store can be used in its place. NOTE: All app-based navigation systems will require the use of a internet hotspot (either a dedicated hotspot or your phone hotspot) for their data, or you will need to download “offline content” prior to using the navi app if you do not have an active hotspot.
  • Can I get a navigation system with the radio that DOES NOT need to use internet data to operate?

    • YES. For situations where you will be traveling and can’t rely on cell coverage, or you have a limited data plan, you can download offline data for Google Maps or the pre-installed iGo Next Gen navigation can be licensed and used on the T-Style radio. Cost for this upgrade is $100 and the upgrade can be done at the time of purchase or at any time after. See the “IGO NEXT GEN NAVI UPGRADE” tab on this page for an overview of the process.
  • If I don’t buy the iGo Next Gen upgrade, do I still have to install the GPS antenna?

    • YES. Installation of the GPS antenna will still be required (or extension used for the factory GPS antenna) when using Google Maps or any app-based navigation system or location-based app.
  • What version of Android does the T-Style Radio system run?

    • Android 8.1
  • Can you upgrade the Android version?

    • No.  All of the CANBUS protocols for this unit have been written to work on the 8.1 platform.
  • How big is the built-in hard drive on the GEN 4 T-Style radios?

    • 64GB w/4GB of RAM.  A note of caution: the more memory you use for applications and media, the more likely to affect the speed of the system.
  • Can I go online with the T-Style radios?

    • Yes.  The T-Style radios are Android tablets, and so are able to do the majority of the same things a standard tablet can do – things like access to the Google Play store for apps, a web browser for internet exploring, etc.  The system will require an internet hotspot of some sort, either from your home’s Wi-Fi, your internet provider local hotspots, Wi-Fi built into the vehicle or your cell phone’s hotspot.
  • Does the T-Style have a built SIM Card that I can activate with my cell phone provider?

    • No.  The system requires an outside hotspot to make the internet browser and online applications work.
  • Can I connect a T-Style Radio to aftermarket amplifiers?

    • Yes.  Front, Rear and Sub RCA outputs allow you to connect to your aftermarket amplifiers.  The RCA output is a low voltage so if you plan on building a high end system, we suggest using a 3rd party DSP or Line Driver to up the voltage on the RCA.
  • How do I know if there are firmware updates that are designed for my radio?

    • All units we ship have been updated to at least the APP 4.4 version, which gives you the ability to check for updates right on the radio. 
  • How do I update my system to the latest firmware?

    • When connected to a home or office Wi-Fi network, click the “SETTINGS>SYSTEM>UPGRADE” tab on the radio to check for updates. If it finds an update, it will ask you to install it. It would be beneficial to check for updates at least every 30-45 days.
  • When I try to update firmware, I get “config file not found” error

    • This failure may be related to using a hotspot connection. Do not try to do updates when connected to a hotspot if at all possible. Connect to a home or office Wi-Fi network that is capable of high-speed connection, as the APP update is almost 1GB in size and will take FOREVER on a standard hotspot connection.
    • Alternatively, this error can be seen if the factory update server is down or in maintenance mode.
  • How long is the warranty?

    • 1 Year.  All Linkswell products have a 1 year replacement warranty from time of purchase.
  • Is this system the same as the other brands out there?

    • NO!  Linkswell is not related to any of the other brands selling a similar-looking product.  Linkswell has their own product development team and software engineers that do product development out of their Southern California office. Others, notably the Rhino and Phoenix Android radios, are based out of China and have little to no North American presence or support. ADC Mobile will not sell other brands, as we have not determined that their commitment to quality is the equal of Linkswell.


  • Can I do the installation myself? How difficult is it and how long should it take?

    • YES! However, it depends entirely on your skill level and your willingness to approach the installation with care and caution.  You should be familiar with hand tools and be able to follow instructions IN THE ORDER GIVEN. You will absolutely need to take your time, read the instructions, watch our videos and do a methodical, step by step install. Fully 80% of our customers do it themselves, with guidance from the paperwork included with the unit and by watching the installation and demonstration videos. We will try as much as possible to assist you in attempting the installation yourself, with phone support from installers with decades of experience.
    • We categorize this install at a 2-3 on a 10 scale of difficulty (again, provided you read the instructions and watch the videos), as there no operations that require anything more than basic hand tools and reasonable care to complete. On this system, most people will do the installation start to finish in under 4 hours.
  • Is there anything I need to do on the factory radio before I remove it?

    • POSSIBLY. If you have a factory hotspot built into the truck, the factory radio is where the password for that hotspot is stored. In order to not have to reinstall the factory radio, take a picture of your factory hotspot info screen with the password. :- )
  • Are there any tips or tricks that will make the installation easier or minimize the possibility of damage to the radio or my truck?

    • YES! We have over 110 years of professional installation experience on the ADC Mobile staff and we’re happy to pass along “best practices” to help with your install – feel free to call us if you get stuck on any step, and we’ll be happy to help. Here are some of the major tips that will help your installation go smoothly:
      • Use the right tools: This installation will require 7 & 10mm sockets, plastic trims tools, a pick or a small flat blade screwdriver and some small zip ties.
      • Protect the new radio and the truck: Don’t do any work in the truck before bringing a blanket from the house and covering the center console of the truck so that you don’t have to worry about scratching the radio bezel or the truck’s console. Nothing will wreck your day faster than ruining the finish on your new radio!
      • Take your time! Allow plenty of time for the installation and setup of your new radio. Rushing the install or not covering all of the setup steps required once it’s up and running adds to your frustration and to ours. Do the install on a weekend when the truck doesn’t need to be used. Do the setup when you can spend the time to learn the system and explore all of the menus.
      • Have an extra set of hands available: Since this is a BIG radio with a lot of harnesses attached to it, a second set of hands will definitely make things easier. Try to line up a spouse or a friend to lend a hand when it comes time to make all of your connections.
      • DO NOT PRY PLASTIC PANELS APART WITH METAL TOOLS! To remove the trim around the factory radio, we suggest that you use a plastic trim tool. These are readily available online or in your local auto parts store, and most sets cost less than $10.
      • The metal clips that hold the factory radio trim into the dashboard will need to be swapped to the new radio. You can use a small pick or flat blade screwdriver to remove these clips, but do this on your kitchen table – don’t swap them inside the truck where they can fall on the floor and get lost. Leave the plastic film on the radio and new trim bezels, and consider laying a soft cloth or towel down as you install the clips onto the radio and bezel pieces.
      • Make sure to check your work, and test the system BEFORE you bolt it all back together! There will be nothing more frustrating than getting the system all done and bolted back in only to find that you overlooked a connector or have something plugged into the wrong spot. Although you may want to admire the finished product ASAP, do yourself a favor and check ALL FUNCTIONS before you bolt it back in.
        • Make sure the radio works and it pulls in stations on both AM & FM. If FM works and AM does not, check the connection on the antenna adapter.
        • Make sure all USB ports charge your phone and play digital media
        • Make sure the Bluetooth system works and that you can make calls using the outboard microphone. If not, make sure the microphone is plugged in tight.
        • Make sure the steering wheel controls work.
        • Make sure the HVAC system is set and works properly. THIS IS A MANDATORY PROGRAMMING STEP – DO NOT FORGET ABOUT IT.
        • Make sure the radio can pair to your hotspot and that it connects to the internet. If not, make sure the blade type antenna is installed and tight and that you are entering the password properly. 
        • Make sure the backup camera works.
        • Make sure Google Maps (or iGo Next Gen navigation, if purchased) is able to get a GPS fix. If not, check the GPS antenna connection.
        • (OPTIONAL) Make sure the DVR camera operates. If not, check the USB connection and that the connection in its harness is plugged in tight.
  • Do you have any tips if I have this professionally installed?

    • YES! If you choose to have a professional installer do the installation, we HIGHLY recommend that you encourage them to watch the installation video in order to familiarize himself with the process. Most professional installers have never seen these types of radios, and so are not familiar with every step required for a successful installation (and most of them HATE reading manuals or watching installation videos). We have had many instances of customers calling because portions of their systems did not work as intended, and the majority were caused by the installer overlooking all of the connections that needed to be made, and not testing the system before delivery.
    • If you do decide to have it professionally installed, we will gladly talk to your installer to pass along our tips and tricks.
  • The installation guide included with the unit is not very explicit. How can I find more information on the installation process?

    • We agree that the installation guide included with the system is pretty bare-bones. We HIGHLY recommend that you watch the installation video and review all of the other material on this page in order to familiarize yourself with the system.
  • My truck’s radio doesn’t look like the one in the installation video – is my installation different?

    • The installation video will be same regardless of which factory radio was originally installed. 
  • Are there any particular tips regarding this radio installation I need to know?

    • YES. When tightening the large radio chassis into the dashboard, do the fitting very gently, carefully aligning the new radio into the factory bezel, then screw in all of the factory screws LOOSELY to begin with. This allows you to insure the radio is going in FLAT and TIGHT.

      Once you have all the screws inserted and you know the radio is centered and tight to the dash, then hand-tighten the screws in a criss-cross pattern (like tightening a wheel on your vehicle) in order to make sure the radio doesn’t distort the dashboard or add stress to the display that may cause “phantom fingers” issues after installation.


  • Does the GPS antenna need to be mounted outside or need to be visible in the truck?

    • NO. The GPS antenna does not need to be mounted outside the truck and does not need to be visible inside the truck. As long as there is no metal between the top of the GPS antenna and its view of the sky, it can be mounted almost anywhere. We normally mount it under the dashboard in the area to the right of the defroster vent under the trim at the base of the windshield.
  • What is the blade-style antenna for and do I need to use it?

    • This antenna is the wifi antenna and is required to be used in order for the radio to pick up wifi signal from the truck or phone’s hotspot. Be sure to snugly tighten it with a wrench (DO NOT OVERTIGHTEN) before finalizing the installation so it will not loosen over time.
  • My truck came with factory navigation – can I re-use the factory GPS antenna with the T-Style radio?

    • We do not recommend it due to tolerance differences that may result in intermittent GPS reception.
  • Do I need to use all of  the harnesses supplied with the radio?

    • We do recommend plugging in all of the additional plugs that came with system into the proper ports on the back of the unit, regardless of whether you intend to use them or not, simply so that if you ever decide in the future to add amplifiers or other accessories, all of the plugs will be there instead of getting lost in the garage somewhere…


IMPORTANT: Open the box that contains all of the harnesses and adapters that shipped with the unit and lay them out on a table or bench so that all the parts and pieces can be identified and not get lost.

We get a lot of tech calls from customers that swear they are missing a harness, when in fact it has fallen out of the truck, between the seats, etc. We have never seen a unit ship without all of the harnesses that are supposed to be there…


Are there any particular tips regarding this radio installation I need to know?

YES! The two blank square trim pieces on the right and left side of the trim bezel are there to allow access to the bottom set of 10mm bolts that hold in the radio. These pop out easily from behind when doing the install to allow you to insert the bolts when finishing the installation.

Because the two bolts are going to be reinstalled “blind” (you won’t be able to hold them in place in the socket with the radio in place), use the trick shown in the video above (see 4:45 in the video) to use electrical tape or a magnetic socket to reinstall the bolts – this will make your life MUCH easier! :- )

DO NOT REINSTALL THE BLANK PLATES IN THESE LOCATIONS BEFORE TESTING EVERY FUNCTION! These blanks are not easy to remove from the front, and if you have inserted them prior to testing all functions and need to remove the radio for any reason, you will need to remove them again to gain access to the 10mm bolts, increasing the chance you may damage them.

2020 Tundra Factory Amp Turn-on:

On Non-JBL 2020 Tundras, you may have a factory amplifier that runs the speakers in all four doors that may not be triggered properly in the Linkswell harness. This will result in sound coming from ONLY the front and rear tweeters. If this is the case, you will need to verify that the factory amplifier is being turned on.

There is a factory amp turn-on wire in the factory harness (as show below) that requires a 12 volt input to turn on the factory amplifier. If this lead is not populated on your 2020 Tundra Linkswell harness, you will need to tap the ORANGE “AMP EN” lead from the Linkswell harness into the SKY BLUE factory wire as shown below:


The GEN4 T-Style radio comes with multiple additional accessory plugs that will be required for your installation. The image below shows the proper locations for all of the accessory plugs.

Even though these plugs are keyed to help locate them into the proper ports, it is possible to plug some of them in incorrectly. NOTE: It is extremely important that all plugs are plugged into the proper ports in order for all accessories to operate properly! Damage to accessories or to the radio may result from improperly located accessory plugs! 

We highly recommend that you plug in ALL of the plugs to the their proper ports even if you are not using them in order to not lose them – for instance, if you ever decide to add amplifiers to your system, you will need the RCA output harness. If that plug is plugged in already, you can’t lose it in the garage somewhere… :- )

Microphone placement:

When deciding where to place the included microphone (YES, IT IS REQUIRED TO USE IT), the goal is to mount the mic where it will get the least amount of vibration and wind noise transmitted to the mic. Avoid the temptation to take shortcuts while running the mic! Don’t mount it on the dashboard or clip it to the “A”-pillar cover, as sound quality will suffer.

After much experimentation (including trying to incorporate the factory microphone into the Linkswell system), we have found the best place to mount the mic is up near the rearview mirror as shown here:

What we have done is simply zip-tied the mic wire to the harness that runs down to the rearview mirror and let the mic hang down vertically. This will eliminate, as much as possible, the amount of vibration that the truck is able to feed into the mic, and will result in much better overall better sound quality – if done properly, it will sound BETTER than the factory Bluetooth.



Due to a conflict between the Android system clock and the radio’s clock, the Android system clock will need to be set manually in order to maintain accurate time when the vehicle is shut off and restarted.

Go to “Settings” > “System” > “Android” > “System

Scroll to “Date & Time

Turn off “Automatic date & time

Turn off “Automatic time zone

Set the date, time and time zone manually for your location



USB Connections


The GEN4 radio made a change in how you will accomplish Car Play & Android Auto – it no longer requires an outboard dongle to allow those functions – you now will plug the phone’s charging cable directly to the USB input without using a dongle. However, the GEN4 radio now has three USB inputs – on the RED PLUG is a standard female “A” type USB labeled “Phonelink” and one is a mini female “B” type USB designed to plug into the factory USB harness and activate the factory USB input. On the WHITE PLUG is a standard USB female.



Android phones can use either of the Linkswell radio’s standard Female USB inputs to accomplish Android Auto and so do not need any special treatment of the USB connections. You can connect either the black or green factory USB cables at the HMI module to the square factory USB connector on the radio and using the supplied mini “B” female to male “A” adapter, you can connect the other factory USB cable to the “Phonelink” USB input, and you should be able to operate Android Auto using both of the factory USB ports without issue.


To allow Car Play, voltage switching occurs in the radio and only the Phonelink port does that. To do Car Play, iPhones must use a direct connection to the USB input labeled “Phonelink”. This means that your iPhone must be connected to the Phonelink USB input directly and not through any other hubs or adaptersINCLUDING THE FACTORY USB HUB WITH THE SD CARD READER.

To accomplish a cleaner installation to use the Phonelink input for using Car Play while still using the factory USB hub, follow the methods below:

Method 1: Source a longer USB-Lightning charging cable (like the one shown below) – plug it into the “Phonelink” USB and run it to your preferred location (center box, console storage, etc.). 
Method 2: Source a USB M-F adapter (like the one shown below)that extends the “Phonelink” female USB to an external location, and mount in your preferred location. 


Tech Tips

If you read the owner’s Manual, watched the installation video, and followed the installation & setup steps and still are having issues, some of the common things to check are listed below:

  • Screen controls are backwards/upside down! 

    • Sometimes if you have the radio powered on while fitting the radio back into the dashboard, the radio will go into “calibration mode”, and leave you with mixed up touch controls. 
    • To fix, restart the radio and when it is booted up, place five fingers on the touchscreen, then follow the instructions to recalibrate the screen.
  • Radio won’t power on:

    • Overwhelmingly, issues with the radio not turning on are related to the connectors either not being plugged in or not being seated properly – we recommend that all connections made to factory connectors are plugged in and given a tug to make sure they are snapped in properly.
    • Make sure that the red data box is SECURELY connected to the Main Harness WHITE plug – this box is what interprets the vehicle data and sends out the 12V to the radio, so it is critical that this be plugged in securely!
  • No Audio:

    • There are two main harnesses shipped with the radio: non-JBL & JBL amplified. These have different connectors and will only connect to the factory harnesses one way – if they fit, you have the right harness.
    • On 2020 non-JBL trucks, there is a chance that you may have an amplifier running the front speakers. If you hear no audio from the front speakers, check power on the BLUE wire as shown in the picture in the “Installation” section.
  • Different audio sources vary in volume, are too low/too loud, or distort when volume is turned up:

    • In the “Settings>Audio” menu, there are “pre-amp gain” level slider controls for all sources in the radio. These govern the relative output for all sources when compared to each other as well as the maximum output that is possible from each source. These controls are designed to be adjustable to give the best output across all sources and should be adjusted depending on your system and the sources you use.

    • The best way to set these gain controls is to lower all of them to “5”, then turn the volume of the radio up to 37-38 (out of the max of 40 on the volume scale), then switch between each source (radio, apps, AUX, USB etc.) and increase the slider control for each source so that at your volume level of 37-38 you get loud, clean output that is relatively the same for each source.

    • If you set the gains this way, you will insure that you will be getting the maximum clean output the radio or amplifier is capable of producing, and that as you switch between sources, all of them are at the same level, lessening the chance that one will be too soft while the other will blow you out of the truck at the same volume level setting.
  • Turn off Notification Chimes:

  • HVAC is not functioning correctly: 

    • You must identify your factory HVAC control type (Manual, Automatic WITHOUT seat heaters or Automatic WITH seat heaters) and follow the programming guide above to set the controls properly. YOU MUST FOLLOW ALL OF THE STEPS LISTED, INCLUDING THE “SAVE AND REBOOT” STEP!
  • HVAC does not operate when remote starting the truck:

    • Auto HVAC controls will not be active when using the factory remote start, since the new radio is not powered up during remote start.
  • Backup Camera will not display:

    • The radio comes with an adapter for the factory camera which converts the camera signal to an RCA male connector for use by the radio. The output RCA connector from the adapter will plug into the “Factory Cam Input” female RCA on the BLACK “camera Inputs” plug, and the BLACK plug will plug into the top row, far left port as you are looking at the back of the radio (next to the blue GPS connector).
    • If your truck came with a camera display built into the factory mirror, this will need to be hardwired in order to display on the T-Style radio. Please call for guidance prior to attempting this modification.
  • I checked my plugs and the camera still will not display!

    • There is a setting in the “Factory Settings” menu that has the ability to turn off the camera input in the “B” series units – this is the “HDMI Input” setting, which must be turned “OFF”.
    • To check this settings, go to “Settings>System>Factory Settings>1660>Install Set” and look for the setting for “HDMI Input”. This must be turned OFF:
    • On “A” series units (those with HDMI input), this setting should be set to “ON”.
  • Backup Camera displays but colors are too dark:

    • Place the truck in reverse to display the backup camera screen, then tap the dark bar at the top of the screen – a video control should pop up in the top left corner – choose “default” in that control to reset the brightness of the backup camera display
  • Factory USB port does not work:

    • The factory USB port plugs into the square factory-style mini-USB female connector on the RED USB harness of the radio, and the RED plug plugs into the back of the radio – top row, far right as you are looking at the back of the radio (next to the radio antenna).
  • PhoneLink app does not work at all:

    • Car Play requires that the phone’s charging cable to be plugged directly into the “PhoneLink” USB input.
    • NOTE: Android Auto does not care what USB port is used
    • Make sure the setting for “Auto run Car Auto” is set to “ON” in “Settings>System>Factory Settings>1660>User Settings”
  • Car Play does not work:

    • Car Play requires that the phone’s charging cable to be plugged directly into the “PhoneLink” USB input.
    • NOTE: The PhoneLink functionality is not guaranteed using aftermarket phone charging cables. In order to insure the best operation, ONLY use the charging cable that came with your phone.
    • Check for updates for the ZLINK app in the “T-Style Apps” section above. Uninstall the ZLINK app first, then download and install the new version.
  • PhoneLink App stuck on Waiting (won’t connect):

    • Go to “Settings > System > Factory Settings>1660>User Settings”. Change “Car Auto Apple” and “Car Auto Android” to “Charge Only”, then change it back to “Mobile Connection”. Press “Save and Reboot” to make sure the setting sets properly.
    • Car Play requires that the phone’s charging cable to be plugged directly into the “PhoneLink” USB input on the RED colored plug – it cannot operate when plugged into the factory USB hub.
    • Make sure you are using a Genuine Apple cable, or reputable brand (Anker, for example). Some cables are for charging only, or are not Car Play compatible.
  • PhoneLink App says “Please insert into OTG Socket”:

    • Make sure the charging cable is plugged into “PhoneLink” USB Port.
  • My Android phone won’t activate the Android Auto feature

    • Since the Android Auto feature of the radio will only allow display in the upper half of the screen, WE DO NOT RECOMMEND THAT YOU USE ANDROID AUTO, since all Android apps that run on Android Auto will also run natively on the radio, with a better display.
    • The PhoneLink functionality is not guaranteed using aftermarket phone charging cables. In order to insure the best operation, ONLY use the charging cable that came with your phone.
  • Car Play skips two tracks from steering wheel controls:

    • Two updates need to be done, in order.
    • 1st: Update the APP: follow the firmware update procedure to do this update
    • 2nd: Update the ZLink app from the link in the T-Style Apps section above
  • Disable sound muting while in reverse:

    • Go to settings
    • Go to system

    • Go to Factory Settings
    • Enter 1660
    • Go to Install Set
    • Turn “Show Door State” OFF
  • Change Network Settings to Fix iPhone Hotspot Issues:

    • Go to Settings
    • Go to System
    • Go to Android Settings
    • Go to the “Network & Internet” section.
    • Go to the “Data Usage” section
    • Go to the “Network Restrictions” section
    • Identify the Wi-Fi source you are using (should be your iPhone name)
    • If it says “Automatic” under the name, tap on the name and choose “Not Metered”
    • Do the same for all other Wi-Fi sources if you use other hotspots as well
  • Why does the clock keep changing time on my T-Style Radio?

    • The system receives data for the clock from a few different sources which can sometimes cause the clock to change times.  To fix the clock issues, follow these steps:
      • Go to “Settings”
      • Then “More Settings”
      • Scroll to find “Date & Time”
      • Be sure you turn off all the “Automatic” settings
      • After turning off all Automatic settings go to manually set “Time Zone”
        • (You have to set the time zone before you change the time or the time will revert to the time zone that it is set at)
      • After setting the time Zone the clock should show the correct time.
        • If the clock skips an hour:
          • Go back to “General Settings”
          • Press the clock Icon and switch the “DST” option
          • If that doesn’t fix it go back to the Time Zone options and select a time zone that makes the time display correctly on the screen.


  • 2-Minute Clock Settings Video:

  • How do I get my iPhone’s contacts to sync to the Bluetooth on my T-Style Radio?

    • iPhones require you to approve the syncing of your contacts to our Bluetooth System.  To do that you use the settings in your phone
    • Go to “Settings” on your phone
    • Then “Bluetooth”
    • Find the T-Styles Bluetooth in the list and select the “i” in a circle icon on the right side
    • Then turn on the “Sync Contacts”
  • How do I connect the T-Style radio to the internet so I can run Google Maps and my apps?

    • You must connect the radio to a data source such as a hotspot built into the vehicle, dedicated mobile hotspot or a hotspot built into your cell phone since the T-Style radio needs an internet connection in order to run any app-based navigation system, or any apps that require data.
      • To connect the radio to a wi-fi hotspot, hit “Settings”, then “More Settings” and click on “Wi-Fi” and turn it on. Identify the network you want to use from those displayed and enter the username and password for the network.
      • More than one wi-fi network can be paired to the system, but only one can be active at a time. For instance, you can pair to your home wi-fi network for use while parked in the driveway, and pair your phone’s hotspot for use while driving. If the network pairing doesn’t switch automatically, you must go to “Settings” – “More Settings” – “Wi-Fi” in order to change the network manually.
  • How can I make the “NAVI” button run a different navigation app?

    • The system comes loaded with Google Maps pre-assigned to the “NAVI” icon, but you can have this run any other app instead by assigning i in the “Settings” menu:
      • Open the “Settings” menu and click the top icon on the left side (map pointer). A list of apps will populate the right side.
      • Double-tap the app you want to run with the navigation icon.
      • Tap the check mark (OK) to lock in your choice
  • Some apps in Google Play Store tell me they are incompatible with my version of Android – why?

    • The Android version in this radio is 8.1. Some apps require higher levels of Android in order to install and run. Fortunately, the T-Style radio allows you to install “.apk” (app) files directly through USB, so you can download and install apps without having to go through the Google Play store. This means you can find and download older versions of most apps from “APK Mirror” sites around the world that will be compatible with Android 8.1.
  • I’ve downloaded an APK file – how do I install it?

    • Once you have downloaded your APK file to your computer, copy it to a USB drive, then bring it to the radio and plug it into one of the USB ports. Open File Manager and navigate to the USB drive. Click on the APK file. Open with “package Installer”.  You will be asked if you want to install it. Choose “YES” to install the file. Once installed, it should show up under the App List, where you will be able to click on it to run the app.
  • Why does my screen go black when I turn on my right turn signal?

    • If you have not installed a right-side camera but have that camera enabled in the menu, it will switch over to the right camera screen but display a black screen. To stop this function, go to “Settings” then “System Settings” (the icon with a single gear).  Scroll through and turn off the “Right Camera”.
  • Can I change the background on my T-Style Radio image?

    • Yes. You will need to use the optional “Nova Launcher” app or a similar app that changes the launcher used by the system.

    Can I change the icons on the home screen of my T-Style Radio?

    • Yes. You will need to use the optional “Nova Launcher” app or a similar app that changes the launcher used by the system.
  • When I changed to Nova Launcher, I lost my “Door Ajar” notification on the screen! Can I get it back?

    • No, unless you don’t use a launcher. The door ajar indicator will only display above the factory launcher and apps – once Nova Launcher (or other launcher) is used, they take over he uppermost layer of display, and the door ajar indicator cannot display above that.
  • Why can’t people can’t hear me in Bluetooth calls?

    • You have to be sure you use the separate microphone that came with your T-Style radio.  There is no built-in mic on the face of the radio nor are we able to retain the factory microphone.

Google Maps & iGo Navi Upgrade

The Linkswell GEN4 T-Style radio system comes with the Google Maps app pre-installed for use as the default navigation system, though any navigation app that can be downloaded from the Google Play store can be installed and used as the default system as well. In addition, using the “PhoneLink” app, you can use any compatible Car Play or Android Auto app on your phone for navigation.


This means that in order to run Google Maps or any other Android GPS app you have installed on the radio, you must have a data hotspot in the vehicle and paired to the radio – this can be the factory data hotspot, your phone, a portable hotspot, etc. OR you will need to go into the options for the system and download content that is saved to the radio’s memory so you can access that content without being connected to the internet.

If you want to use Google Maps in the “Offline map mode”, meaning you can use it WITHOUT having to have an active data connection, follow this video to get offline maps set up:


The iGo Next Gen Navigation system upgrade gives you the ability to navigate without consuming data and is pre-installed on your system – it just needs the license file to make it active.

Adding the license is an extra-cost option that can be added when you order, or you can activate the iGo system after your purchase.

In order to do the upgrade after you have purchased the system, here’s the process:

  • Run the “Dev Info” app and on the screen that opens, the “IMEI” number will be shown at the bottom left of the screen
  • Copy the IMEI number EXACTLY. NOTE: There are no refunds for licenses generated for the wrong IMEI number!
  • Purchase the iGo license here:
  • Provide the IMEI number of your unit during checkout
  • We will forward your IMEI number to the manufacturer
  • The manufacturer will generate the license (.lyc file) and we will email it to you
  • Follow the instructions below to install

Installation of iGo Next-Gen navigation license file:

  • Save the “lyc” file we send you to a USB stick
  • Insert the USB stick into a USB port in the truck
  • Open File Manager app
  • You will have “FLASH” and “USB” drive icons on the left column – click on the “USB” drive
  • You should now see the “.lyc” file you copied to the USB drive – tap on the box on the far right of the file name to highlight the file (this adds a checkmark to the box)
  • Hit the “Copy” icon (bottom of screen – icon on left)
  • Tap the “Flash” icon (top left)
  • Tap “iGo” folder to open it
  • Tap the “license” folder to open it
  • Tap the “Paste” icon (bottom of screen – icon on left) – this will paste the file into the “license” folder
  • Now start the iGo system and it will walk you through the setup process

If you want iGo to be the default navigation app, open “Settings”. The navigation icon (top icon) should be lit. Double-tap the iGo NextGen icon in the list at right. Tap the checkmark to verify your selection. iGo will now open when you touch the “Navi” icon on the bottom bar or on the Home screen.
