We have reviewed almost every “factory look” deck on the market, and we’re extremely confident in stating that the Car Show is far and away the class of the field. When we’ve compared features, technical support, firmware updating, warranty, return rate, and overall customer experience with this unit versus the others, and we don’t hesitate for a second to recommend the Car Show as THE BEST navigation option for 2007-14 GM vehicles. (I have one in my 2011 Tahoe – Walt Ottenad, Owner, ADC Mobile)
2007-2014 GM vehicles present a challenging environment to install aftermarket navigation units into, with the requirement that any replacement aftermarket navigation system function seamlessly with the the CAN BUS network that ties all of the onboard computers together. There are thousands of lines of code governing the information being transmitted by the vehicle’s Powertrain Control Module (PCM), Electronics Control Module (ECM), Body Control Module (BCM) etc.The radio/navigation system is treated by the vehicle as another Control Module – an integral part of the LAN BUS communication system, being tasked with providing control for different modules such as the XM Satellite Radio tuner, and functioning as the amplifier for passing warnings (chimes) and other information (OnStar, factory Bluetooth) from the vehicle to the driver.
In contrast to universal aftermarket navigation systems from Alpine/JVC/Kenwood/Pioneer etc., that require up to $200 worth of adapters just to function in these vehicles (see chart below), Car Show engineers have programmed all the necessary code into the unit to allow it function in an almost identical fashion to the factory head unit, so there are no other adapters or modules required to install it. It truly is a “Plug and Play” installation, with no modifications required to the vehicle whatsoever.
The aftermarket navigation units also require a plastic trim kit to be able to bolt in, with varying cosmetic results, and which very obviously look aftermarket when installed. The look of the GM1210-CA is as close to the factory navi as is possible, considerably reducing the chance for theft, as the factory navigation systems are FAR less likely to be stolen than high-end aftermarket units.

When GM changed to the new body style trucks in 2007 and incorporated the DVD-based navigation system, the factory navigation system was decent compared to the options in the aftermarket at the time, but since development in vehicle navigation and entertainment systems is measured in dog-years, by the time they were phased out in 2011 (in favor of the new HDD based GM navi that came in some 2012 GM vehicles), they had become VERY old and tired, with an embarrassing lack of features compared to aftermarket units.
Although factory GM units are still available for some 2007-2011 GM vehicles, you should think VERY carefully about what features are most important for you before you decide.
For instance, the factory navigation system will require you to spend over $200 on a “bypass module” in order to change your destination or allow your passenger to watch the internal DVD while driving – these features are possible with the GM1210-CA without any additional expense.
2007-2011 GM trucks and SUV’s use the same radio chassis and electrical protocol as the Car Show unit and so can be swapped fairly easily to take advantage of the additional features of the GM1210-CA. Most vehicles with factory navigation and factory rear entertainment also have the Bose Centerpoint audio system (see above), which does not require any additional adapters to work with the GM1210-CA.
Yes. Factory GM navigation head units with a current map DVD and GPS antenna fetch between up to $600 on EBay. This makes the swap to the GM1210-CA probably the most cost-effective upgrade you can do to an older GM vehicle.
No. 2012-2013 GM vehicles with factory navigation have a completely different set of plugs on the radio chassis.
The GM1210-CA retains almost all factory functions for almost all applications. It works with all current GM functions except LDS – Lane Departure System. Warnings, OnStar, OnStar, Steering Wheel Controls, Factory Bluetooth, Overhead Rear Video and Rear Seat Audio all work as they currently do. However, there are some functions known to be incompatible with the GM1210-CA:

  • You cannot change XM stations from Rear Seat Audio controls. All other RSE controls should operate as normal.
  • GM OnStar contains the GM Bluetooth. This remains working in all GM cars. The steering wheel controls in GM will continue to operate the GM Bluetooth, not the Car Show Bluetooth. This is normal and cannot be changed or the OnStar system could not be controlled. The Car Show Bluetooth can be used by utilizing the on screen controls.
  • Not compatible with “Cargo Area Audio Controls” in the GMC Acadia. These come in the Technology Package.
Possibly. For instance, we know that the GM1210-CA will work without significant issues in almost all 2007 model year vehicles, but there are a number of different scenarios that impact whether or not you’ll be able to use the GM1210-CA in your application, and most have to do with the CAN codes in place in your vehicle and whether Car Show has programmed these codes into the GM1210-CA. The list above contains the applications that Car Show has proven to work with the the unit.
If your vehicle is not listed, but has a radio that is functionally the same as the models and years listed above, then it MAY be possible to add the GM1210-CA to a vehicle that it’s not currently certified for. In these applications there is no guarantee that any particular vehicle or radio function will work.
This timing varies depending on a number of factors. If you are entering the vehicle after the unit has been off for a period of time, we’ve measured bootup times between 12 and 18 seconds. If you turn off the vehicle and start it right up again, bootup is almost instantaneous.
There “may” be no lights on, low fuel or door lock warning chimes. Other chimes and warnings should be present.
Yes, just like the factory head unit, the GM1210-CA will stay on for up to 20 minutes after the key is shut off and the door is not opened.
Yes. The GM1210-CA comes set up to plug and play into the base GM (non-Bose) audio system.
No. The GM1210-CA has a supplied harness that will be used to make it compatible with the factory Bose amplifier.
All cables and adapters are included with the GM1210-CA to allow installation in all Bose & non-Bose vehicles in the application chart: power/speaker harnesses, aftermarket and factory rear entertainment harnesses, camera/AV2 harness, antenna adapter, GPS antenna, USB adapter harness and RCA amplifier and subwoofer output harnesses.
Yes. The GM1210-CA is one of the only units able to turn on the Bose Centerpoint amplifiers w/o special adapters or modules.
The easiest way to tell if a vehicle has the Bose Centerpoint system is to look for the presence of a center speaker, the “DTS” logo on the face of the factory radio, or the code “UQA” on the silver options tag inside the glovebox.
The GM1210-CA matches the factory GM green backlighting only. It does not have the ability to change colors on the backlighting to match the Acadia.
Yes. The GM1210-CA has a backup camera input included that will accept any standard backup camera, including the factory camera that displays in the rear view mirror (if equipped). Additional cabling is required to incorporate the factory camera into the GM1210-CA. However, the factory GM camera in the Silverado/Sierra is generally far lower in quality than the aftermarket camera kit we sell.
Yes. The cabling required to route the camera to the GM1210-CA does not interfere with the factory display, thus allowing both the mirror and the GM1210-CA to display the factory camera’s picture.

Our CS-GMTRB camera system allows a far better than factory camera to be installed in the factory GM bezel for an exact factory look. This kit can be installed in 2007-2014 Silverado and Sierra pickups.

Yes. We carry cameras that mount on the liftgate of the GM SUV’s, that comes with guidelines and a much better sensor than factory that gives much better night vision and a much clearer picture than the factory camera.

Yes, but the camera must be wired to ignition or accessory power. Factory cameras must be rewired to allow this operation.

You will normally see the backup camera display 7-10 seconds after a “cold start” when the vehicle is put into reverse. If you have tied the GM1210-CA into the factory camera’s output that is displayed in the mirror, the delay on the GM1210-CA will not affect the display on the mirror.

Yes. The GM1210-CA allows an audible warning just like factory.

Yes. ADC Mobile has over 900 custom splash screens that allow each unit to be customized to the vehicle in which it’s installed.

Yes. The splash screen format is 24 bit .bmp

Firmware updates are always free, but are unlikely to be updated in the future due to the maturity of the vehicles they are designed to be installed in. Firmware can always be reloaded to insure smooth operation or to fix miscellaneous issues.

Absolutely! One little-know fact is that the factory GM systems are designed to reduce the bass output as the volume is increased, leading to reduced low end output at higher volume levels, ESPECIALLY in the base audio systems (non-Bose). The GM1210-CA has 45 watts per channel (45W x 4), and full output across the entire volume control, allowing much better low bass response at higher volume. Combined with a 3 Band EQ with adjustable crossover points and loudness control, installing the GM1210-CA will definitely give an improvement you can hear.

Absolutely! One little-know fact is that the factory GM systems are designed to reduce the bass output as the volume is increased, leading to reduced low end output at higher volume levels, and although this effect is not as apparent in the Bose audio system as it is in the base radio, it is still significant. The GM1210-CA has full output across the entire volume control, allowing much better low bass response at higher volume. Combined with a 9 Band EQ and loudness control, installing the GM1210-CA will definitely give an improvement you can hear.

In our opinion, the speaker system in the base truck is not great, but not extremely terrible either. By installing the GM1210-CA, you will see a big improvement in sound quality, so we recommend driving the vehicle for a couple weeks to determine what, if anything you feel you would need to upgrade in the factory speaker system. What we generally see when we swap out the factory speakers is that the system takes a HUGE hit in bass response, which means that unless you add some sort of subwoofer in the process, it’s not a great idea to swap out the factory speakers only. We suggest speaker upgrades in this order:

  • Subwoofer (either self-powered or with an additional amplifier, using the subwoofer output of the GM1210-CA) – the biggest bang for the buck there is in car audio!
  • Additional tweeters or replacement front speakers (2-Way, 3-Way or component speakers with crossovers)
  • Rear speakers (generally should be the last thing you spend money on)
Unless you’re going to strip the entire Bose audio system from the vehicle ( amplifier and all speakers), there’s not much you can do to improve the audio quality of the Bose system. The Bose system has speakers that are incompatible with most, if not all aftermarket replacements, so there’s not much out there to even attempt an upgrade with. There are some aftermarket sound processors that claim to improve the quality of the factory system, but we have yet to try them.

No. It has no internal storage capabilities for music or video.

Yes. The SD card will allow the playback of music, photos and video files. Video must be re-encoded to a smaller size and bitrate to be compatible. More information is available in our Support section.

No. It contains a standard AM/FM tuner only and is not upgrade-able to HD Radio.

Yes. Just like the factory GM radio, the GM1210-CA has an RDS tuner which will allow full data display of song/artist/station data if the radio station you’re listening to transmits it.

Yes. The GM1210-CA allows the addition of an aftermarket Sirius/XM satellite radio tuner with additional (optional) hardware
No. It only reads the output of the factory XM tuner, so it doesn’t require you do to anything to maintain XM satellite radio. If your subscription has lapsed, you can find the Radio ID required to renew your subscription at channel 0.

No. The GM1210-CA supports 12 AM, 18 FM and 18 XM presets, only accessible while in each source.

>It has a 3 band equalizer with three crossover points in each band, built-in and user presets, as well as a loudness control and full front-rear and left-right fader and balance controls. If used with an outboard amplifiers for an optional subwoofer, there are subwoofer controls for crossover and output level.

Yes, the GM1210-CA comes with an adapter harness that allows the factory rear entertainment screen to display the DVD, AV1 and AV2 sources..

Yes. The “AV1” and “AV2” inputs allow analog audio and video sources to be displayed on the GM1210-CA as well as be directed to the rear entertainment screen(s). We sell an HDMI-AV adapter cable that allows phones, tablets and other HDMI devices to be used as sources – see the “related products” for more information on this cable.

Yes. With the “Rear Entertainment” Dual Zone controls, the rear seat passengers can watch a DVD or AV1/AV2 source while front seat passengers can enjoy any other source. Audio from the vehicle speakers will be the source that is being played up front, while DVD/AV1/AV2 audio will be available on headphones for rear seat passengers.

With some restrictions – all audio sources will still be available from the rear console headphone outputs, but XM and AM/FM channels will no longer be able to be changed. The factory remote control will no longer control head unit functions.

Yes, the GM1210-CA has standard Red, White & Yellow female RCA outputs for connection to any aftermarket rear entertainment overhead or headrest monitor(s).

Yes, the factory USB jack plugs into the USB cable on the GM1210-CA.

The GM1210-CA comes with a female USB extension harness that can be routed into the glove box or under the dashboard, but if you want to add a factory style USB port, you can purchase the GM USB port and swap out a power port. There are also USB extension cables available to allow center console glove box installations.

Yes. Our optional HDMI-AV cable allows you to convert the phone’s video output to be used on the GM1210-CA.

The GM1210-CA is fully “Apple-certified” and allows full album art, artist & song data, as well as full control of audio and video playback on all late model iPods and iPhones. Some prior versions of the iPod are not fully compatible with the GM1210-CA.

Yes. Our optional HDMI-AV cable allows you to convert the phone’s video output to be used on the GM1210-CA.

Yes. The USB will allow the playback of music, photos and video files. Video must be re-encoded to a smaller size and bitrate to be compatible. More information is available in our Support section.

Yes, DVD playback on the GM1210-CA’s screen is possible when stopped. It supports 16:9 and 4:3 viewing modes. It comes factory set to play DVD Region 1 (North America) discs only.

The unit monitors the parking brake lead and will only allow video playback on the screen when the emergency brake is engaged and this lead is grounded. The parking brake lead must be grounded to allow video playback while moving for test purposes only. DVD playback is always available on the rear entertainment screen.

The CD/DVD drive is capable of accepting one disc at a time.

Yes. The GM1210-CA supports CD audio discs and displays the type of disc currently inserted, title number, track number, elapsed time, file, folder, and stop/play/pause status information. It also allows shuffle, repeat and direct access to audio files on CD discs.The unit plays MP3 songs in the order they were burned on to the disc. The unit will play a MP3 disc with up to 500 songs and/or 200 different folders. You can view and navigate between folders and files with the controls on-screen.

Yes, the GM1210-CA comes with four channel RCA outputs for adding a standard four channel amplifier, as well as a subwoofer output with full subwoofer crossover and level controls accessible from the audio menu. Outputs are rated at 2 volts.

No. The Parrot Bluetooth system in the GM1210-CA functions in addition to the factory Bluetooth. You can choose which system to use at any time, or pair different phones (his/hers) to each system.

Yes and no. The factory steering wheel control will only control the factory Bluetooth system – operation of the Car Show’s Bluetooth is from the touch screen only. For GM Vehicles with OnStar and factory Bluetooth systems – The steering wheel/voice controls will continue to operate the factory systems. If you prefer to use only the factory equipped Bluetooth System, we recommend you turn off the Bluetooth in the Car Show system’s Bluetooth menu so it does not conflict with your factory installed Bluetooth system.
If you do not have factory Bluetooth but have OnStar, your steering wheel controls will operate the OnStar system only. This is normal operation. All other Audio controls will work normally.

No. The Car Show uses both and internal and an external, wired microphone. The external mic is HIGHLY recommended for the use of the GM1210-CA’s Bluetooth hands-free system.

The Car Show system accesses the voice dialing capabilities of your phone, so as long as your phone supports voice dialing, that function will be available when using the Bluetooth system on the GM1210-CA.

The GM1210-CA can accept up to five devices and any device can be chosen to connect to the GM1210-CA at any time via the menu.

Yes. The GM1210-CA can download up to 2000 contacts from any phone and allows alphabetical access to those contacts via the menu. NOTE: not all phones allow contact download via Bluetooth.

Yes, extensive Sent, Received and Missed call logs are available, with the latest call showing at the top of the list.

Yes. You can stream music to the GM1210-CA from any source via A2DP protocol, including music contained on the device or any streaming audio source available on the device.

Bluetooth provides an Advanced Audio Distribution Profile (A2DP) profile for streaming music from a wireless phone or a Portable Multimedia Player (PMP), sometimes referred to as a MP3 player. The unit allows you to play back audio files from your wireless phone or a PMP using a Bluetooth connection. The unit can control a Bluetooth audio player via Audio/Video Remote Control Profile (AVRCP). Bluetooth audio players (or Bluetooth adapters) compatible with these profiles can be connected to this unit. Functionality varies depending on the profile used.
•A2DP: Stream audio from your Bluetooth compatible audio player and listen to the music through the unit.
•AVRCP: Play back, pause, select songs, etc. while streaming audio from your Bluetooth compatible audio player to the unit.
NOTE: Song information (e.g. elapsed playing time, song title, song index, etc.) cannot be displayed on this unit. Since there are a number of Bluetooth audio players available on the market, operations with your Bluetooth audio player using this unit vary greatly. Please refer to the instruction manual that came with your Bluetooth audio player.

Since the GM1210-CA has A2DP Bluetooth Audio Streaming capability, it will support any audio streaming source via Bluetooth. This includes the music contained on your phone or other Bluetooth device when paired. If you are using an Android device, iHeartRadio and Pandora playback will only be available via Bluetooth and will not allow any song data, album art or control – this will only be available on the phone.
If you are using an iPhone, you can stream iHeartRadio or Pandora via Bluetooth, but since the GM1210-CA supports Pandora as a native source when using USB, you can have full control of your Pandora experience, including album art, song and artist data, access to channel lists, next track and thumbs up/down control just by plugging in the USB charging cable and starting your Pandora app on the iPhone.

The GM1210-CA ships with iGo Primo navigation software, which in our opinion is the most capable, most customizable and most informative navigation software currently available from any manufacturer, OEM or aftermarket. iGo Primo allows more data to be displayed than any other system, in more ways, with more clarity and more options and has proven to be extremely reliable and informative.

The map updates are downloaded online to a USB device you provide. Car Show’s FREE “Latest Map Guarantee” insures you’ll have the most current maps loaded in your unit – within 30 days of purchase, log in and download the “NaviExtras Toolbox” from and it will automatically update your map database if required. Subsequent updates will be available at additional cost.

There are no built-in restrictions against using the navigation system while moving. However, entering addresses and other navigation operations requiring data entry should ONLY be done by a passenger or by the driver while stopped.

No. The iGo Primo system does not support any voice-activated functions.

The iGo Primo system supports 2D or 3D viewing modes, with direction of travel or “North Up” display.

Yes. You can set audible and/or visual warnings to warn you when speeding, as well as the threshold (as the percentage in excess of the speed limit) to warn you at.

Yes. The NaviExtras Toolbox allows you to add your own POI lists, as well as import other freely available POI lists available from thousands of websites.

Yes. Using a readily available freeware program, many of the options and interface items such as colors, fonts and text sizes, as well as the ability to override certain “required” inputs can be changed to suit your preferences.

Spoken commands are available in English, Spanish and French. Program languages are Dansk, Deutch, English (UK), English (US), Espanol, Espanol (MX), Francais (CA), Italiano, Nederlands, Norsk, Portuguese, Portuguese (BR).

FAST: Gives a quick route if you can travel at or near the speed limit on all roads. Usually the best selection for fast and normal cars.
SHORT: Gives a short route to minimize the distance to travel.
Usually practical for pedestrians, cyclists or slow vehicles. Searching for a short route regardless of the speed, this route type is rarely practical for normal vehicles.
GREEN: Gives a quick but fuel efficient route based on the fuel consumption data given in Green Routing settings. Travel cost and CO2 emission calculations are estimations only. They cannot take elevations, curves and traffic conditions into account.
EASY: Results in a route with fewer turns and no difficult maneuvers. With this option, you can make iGo Primo take, for example, the freeway instead of a series of smaller roads or streets.

No. Statistical traffic information is stored with the map data, and iGO primo can take that into account when planning a route. In normal cases, these statistics help you avoid usual traffic jams on the given day of week in the given hour, but in some cases like on public vacations that fall on normal weekdays, they can be misleading.

No. There is no capability to add live traffic other than to purchase the optional HDMI-AV cable and display your phone’s live maps.

Yes. It allows you to search for “Green” alternatives for any trip, using lower fuel costs and lower CO2 emissions as your priority when calculating the route.

Yes. When routed via highways and freeways, the system provides a “flyout” display on the map screen showing the availability of your pre-chosen POI’s that are easily accessible at the upcoming three exits on your route.

Yes. The iGo Primo system can generate and save your trip logs that provide a wealth of data, such as tracks of your trip that can overlaid on the map, time-speed-altitude graphs and other information that may then be converted with different tools allowing it to be utilized in Google Maps or in Google Earth.
