Advent OGM1 Installation Guide

Important Pre-installation Notes:

This system is designed for installation by a professional installer, but can be easily accomplished by anyone possessing basic tools and common sense. HOWEVER, there are some basic guidelines to follow prior to attempting the installation:
  • Gather all tools and materials required BEFORE you start the installation, such as plastic trim tools, sockets, crimpers, connectors and zip ties
  • Review the installation videos and installation guides beforehand
  • If possible, bring an iPad or laptop into the vehicle to play the installation video while doing the installation
  • If working in cold weather, WARM THE INTERIOR OF THE VEHICLE PRIOR TO REMOVING ANY PLASTIC TRIM!
  • GO SLOW.
  • If you don’t understand something, review the instructions or watch the video again
  • TEST ALL THE FUNCTIONS PRIOR TO FINISHING THE INSTALLATION – most install-related calls we receive are due to not plugging in the XM radio RCA’s and not removing the two DVD drive shipping screws from the top of the unit.
  • IMPORTANT: Take your time to make certain the radio sits flush on the dashboard prior to tightening screws! Damage to the touchscreen may result from too much stress on the plastic nose piece and WILL NOT be covered under warranty! Be sure to organize the cabling behind the radio in such a way that the radio can lay flat on the mounting surface prior to tightening it down.
  • If you get stuck on anything, call Walt @ 253-297-4570 for guidance

GPS Antenna Mounting

We suggest mounting the Advent GPS antenna in the factory location whenever possible, as this will give you a clear view of the sky without being visible, and delivering the same performance as the factory. Refer to the drawings below to locate the factory navi antenna locations:

Bluetooth microphone mounting tips:

The GM OnStar and factory Bluetooth hands-free systems have a factory microphone that CANNOT be used with the Advent navigation system. The microphone supplied with the OGM1 must be used if you want to have access to the Bluetooth hands-free features built in to the Advent system. This mic is designed to be mounted in free air (free air means that both the front and the back of the mic will be open to the cabin environment) and will usually work the best when it’s mounted on a soft surface (like the headliner) and isolated from any contact with hard surfaces in the vehicle (such as dashboard, trim panels and windshield). Having done literally hundreds of these installations, we recommend mounting the microphone on the headliner as shown below, centered near the rear view mirror, using the large “C” clip that comes with the microphone. Slide the “C” clip over the leading edge of the headliner and attach the mic to the ball end. Be certain that the rear of the clip does not touch the windshield! If necessary, add a small piece of foam tape or a small square of Velcro to insulate the clip from contact with the windshield to reduce any noise that may be transmitted into the mic. You can easily route the microphone cable down the passenger side “A” pillar, then behind the glove box over to the radio.

We recommend the headliner location due to its isolation from vehicle vibrations, the proximity to both driver and passenger, and the distance from sources of noise in the cabin, such as open windows, A/C vents, etc. and have found it to be the best option for the vast majority of vehicles we work on.

XM Radio Connections:

The OGM1 supports the factory XM tuner, and the radio will display XM data simply by plugging in the two main power/speaker plugs, but in order to get the audio to play correctly, the male RCA cables on the main power harness and the female RCA cables on the USB/microphone cable need to be plugged together prior to finalizing the installation:

Advent OGM1 System Setup

When installing the Advent “OE” style navigation systems, there are some steps to take to insure that the installation is done correctly:
  • CRITICAL: Prior to installation, remove the transport screws on the top of the chassis (the two screws under the red WARNING stickers). If you don’t remove these screws, the unit will not accept discs!
Advent transit screws

  • All Advent navi systems have vehicle specific power/speaker/steering wheel control harnesses and most have additional connectors for other inputs or outputs. These additional connections may or may not be used. Refer to the list below to determine if your vehicle requires these connections:
    • RED (IGNITION OUTPUT): This connector is present, but there is no output on the OGM-1
    • YELLOW (CONSTANT 12V OUTPUT): Additional constant 12v
    • BLACK (GROUND OUTPUT): Additional ground
    • BLUE/BLACK (PARKING BRAKE INPUT): Monitors parking brake to prevent video display while driving (may be grounded for constant operation or see “demo mode” explanation below)
    • GREEN/WHITE (REVERSE TRIGGER INPUT): NOT NEEDED ON OGM1 – DECK TRIGGERS VIA DATA
    • BLUE/WHITE (AMP TURN-ON OUTPUT): Required to turn on AFTERMARKET amplifiers or amplifier adaptors (not required on OGM-1 for Bose amps)
    • YELLOW RCA (REAR CAMERA INPUT): Rear camera input for standard rear camera
  • Once the unit is installed, there are some basic settings that need to be covered. FOLLOW THESE INSTRUCTIONS IN THIS ORDER!
    1. Hit “MENU” and then “SETTINGS“, and you’ll come to the first settings screen:
Settings page one
Settings page one
    1. On this page, the first thing you need to do is to “CALIBRATE TOUCH SCREEN” – this is a small calibration routine that sets the locations for the touch-sensitive areas according to where YOU need them to be. Follow the prompts to calibrate the screen, then return to the menu.
    2. Hit “NEXT” to access the second page:
Settings page two
Settings page two
  1. OGM-1 ONLY: Press & hold “SYSTEM RESET” for 15 seconds (until the unit reboots) – this allows the deck to identify its “home” and configure itself for the vehicle in which it’s installed
  2. TURN ON VOLUME sets the volume level every time the deck turns on – set this to your desired volume level or choose LAST VOLUME if you want it to be set at the volume level that was selected when you last left the vehicle
  3. BUTTON BACK LIGHTING sets the lighting level on the hard buttons on the face of the unit – generally left on the “AUTO” setting
  4. TIME ZONE sets your time zone (REQUIRED)
  5. SYSTEM TIME Although the time setting is automatic through GPS, system time needs to be set once
  6. SYSTEM UPDATE is only for use when updating the firmware – if you just purchased the unit, you will have the latest firmware version, but you can always check the Advent OE Navigation Systems page for the latest updates
  • Hit “PREV” and return to the first page to set your rear view camera setting according to whether you’ve added a rear camera or have one present in the system.

BOSE AMP SETTINGS

The OGM-1 only has the ability to be compatible with the standard non-amplified factory system, or the Bose amplified system. The unit ships in the non-amplified mode, but can be easily changed to the Bose mode. You will be able to tell your system is not in the correct mode if the chimes are MUCH louder than they were on the factory deck.
  1. Hit “MENU” and then “SETTINGS“, and you’ll come to the first settings screen:Settings page one
  2. Hit “INFO“, and you’ll see this screen, where you need to tap the “th” in the word “BLUETOOTH”:Info screen
  3. You will then see this menu, allowing you to turn the “FACTORY AMPLIFIER – ON“:Bose amplifier setting
  4. Hit “BACK“, then turn off the key for at least 30 seconds.

DEMO MODE

There is a demo mode that allows the parking brake to be overridden, allowing DVD or iPod video video to be viewed while the vehicle is in motion – this is to be used for demonstration & testing purposes, for off-road use ONLY.
  1. To enable the demo mode, hit “MENU” and then “SETTINGS“, then “NEXT” so you are on the second settings page, then PRESS & HOLD the “SETTINGS” area at the top of the page for 8-10 seconds:
    Demo Mode
    Demo Mode
  2. You will then get the menu displayed below:
    Brake Override
    Brake Override
  3. Choose “BRAKE OVERRIDE – ON” and DO NOT change any other settings on this page. All other settings (Steering Wheel Control, Steering Wheel Buttons, etc) are already set up for your application.

Use Factory Bluetooth & Advent Bluetooth at the Same Time

Posted by Klyde32 in GM-Trucks.com A/V Forum: I have also discovered something that might help with the members who have asked about the OEM mic integration. I noticed today that while driving around, if I hit the transfer button on the OGM-1, it would transfer the call to the trucks OEM bluetooth. I can only assume that it starts using the factory mic. I have an iPhone 4 so I cannot talk to any other phone, but if you are having issues with the sound quality of the OGM-1 mic, you can use the touchscreen to place the call and have access to your contacts/call logs. Then hit transfer and be able to utilize the factory mic. Of course this is only if you have bluetooth from the factory. I know it is an extra step, but at least gets you back to the factory mic. Again, I have had no issues with sound quality on the mic from the OGM-1, just thought I would share the tip. Use “TRANSFER” button to switch to factory Bluetooth

MediaLink Pod Mounting Ideas

Bose equipped Silverado/Sierra/Tahoe/Suburban/Yukon:

We normally mount the MediaLink pod in the center console glovebox mounted vertically on the front wall – we drill a 3/4″ hole to run the cabling forward to the deck, then screw the pod to the front wall. NOTE: If you have the factory USB port in the center console and want to retain it, see the section below
MediaLink in Center Console
MediaLink in Center Console
MediaLink pod in center console
MediaLink in Center Console
Center Console MediaLink Cabling
MediaLink Cabling
This accomplishes a couple things – it keeps your USB sticks from getting broken off in the factory port (or breaking the port itself – we’ve seen both happen) when you toss something in there without thinking about the USB stick that’s sticking out into the glovebox from the factory USB port. Since the USB stick is now vertical at the far forward edge, it’s VERY unobtrusive. Second, if you tend to leave the iPod cable plugged in, you can go ahead and fill the box with stuff without having to worry that anything will interfere with your USB/AUX plugs.

Retain Your Factory GM USB Jack

GM vehicles generally come equipped with two styles of USB jacks – the round “power port” style for the “LT” style trucks and the rectangular “flush mount” for SUV’s and Bose-equipped trucks. All GM USB jacks can be very easily adapted to work with the OGM1 through the use of adapters or cables. This section deals with adapting your factory USB jack to be used with your OGM1.

LT Style Trucks:

LT-style trucks will have the USB jack in the power port (below left). The factory USB jack has a female mini-USB jack on the back (center) that connects via a cable that plugs into the back the radio with a mini-USB male connector (right):
"LT" style USB jack
“LT” style USB jack

In order to retain the factory USB in this system, you can do it two ways:
  • Use a “female mini-USB to male USB” adaptor (below left) and attach it to the factory male connector that used to plug into the factory deck. This will then plug into the Advent’s MediaLink USB input and the entire MediaLink cable can be hidden behind the dash
  • Use a “mini USB male to standard USB male” cable (below right) that will plug directly into the back of the factory jack and the Advent’s MediaLink USB input and the entire MediaLink cable can be hidden behind the dash

Bose-Equipped trucks and SUV’s:

Bose-equipped trucks and SUV’s have a female USB jack mounted in the center glove box or storage box (below left). The factory USB jack has a female mini-USB jack on the back (center) that connects via a cable that plugs into the back the radio with a mini-USB male connector (right):

In order to retain the factory USB in this system, you can do it two ways:
  • Use a “female mini-USB to male USB” adaptor (below left) and attach it to the factory male connector that used to plug into the factory deck. This will then plug into the Advent’s MediaLink USB input in the area behind the radio and the entire MediaLink cable can be hidden behind the dash. NOTE: THIS METHOD MAY NOT BE PRECTICAL DUE TO VERY LIMITED SPACE AVAILABLE BEHIND THE RADIO
  • Route the MediaLink pod into the center console area, then remove the drink tray to gain access to the USB junction (below right). Unplug the junction by lifting up on the chrome tab to release the two cables. The cable coming from the factory USB jack will be the male side (coming in from the right). You will notice a plastic “hood” that protrudes over the top of the male connector – break this off. You will then be able to plug the male USB cable into the female USB jack on the end of the MediaLink pod.

Bosch Relay Basics
Bosch Relay Basics
Relays have been around forever, and in the automotive environment, “Bosch” relays have become the standard, and have been widely copied. These relays are simply the best way to switch power, ground, signal, etc. in a vehicle due to their ability to carry a much higher load (30 amps) than most standard toggle switches, and their ability to be configured in just about any way imaginable to accomplish a multitude of tasks in the vehicle. Relays are really very simple devices – they usually have five terminals; 85,86, 87A, 87 & 30. At rest, the relay’s 30 and 87A terminals are connected (normally closed), allowing whatever is connected to terminal 87A to exit terminal 30 (or vice-versa). When the relay is turned on, terminal 30 is connected to terminal 87, allowing whatever is connected to terminal87 to exit terminal 30 (or vice-versa). Terminals 85 & 86 power the coil that turns on the relay – whenever there is 12 volts (ACC) on one side and ground on the other (it doesn’t matter which is 12v or ground), the relay turns on, connecting terminals 30 & 87. David Levy relay guide To learn MUCH more about the operation of relays and the cool things you can do with them, check out the David Levy Relay Guide. This 44 page guide was published in 1995, and still has dozens of great uses for relays and will help you understand how they can be used to perform many different operations.
Posted in GM-Trucks.com by “Sinkhole”: Hello all. I posted something similar to this several years ago but I thought I’d refresh it for everyone. I always see a lot of talk about DIY installations. As an MECP Advanced certified installer most of the issues I see are due to poor installs and bad wiring connections. I just thought I post a quick little tutorial on how to make proper wiring connection, called a military splice, for those that are not sure. Many will say a soldered connection is better, but this connection has a few very important advantages over solder joints. Not to say that it is better than a soldered connection just that it has a few advantages with none of the disadvantages. First is a military splice can be undone easily if you choose to remove the equipment from the vehicle. Second you are not working with a high heat source in a confined area, thus there is no risk of accidentally melting the insulation on another wire. Also this connection is as reliable and strong as a solder connection if done properly.

TROUBLESHOOTING TIPS:

  • Unit never boots up (doesn’t reach the main menu): This is a sign that the firmware is corrupted, and here’s what you need to do to fix it: Go to http://voxxintlcorp.com/downloads/OGM1/ and download a new firmware file and print off the instructions, but instead of going into the menu to start the update (which you can never do since it won’t boot up), press & hold the screen when you turn the key on then release when it turns green. You will now see the keypad where you can enter the code (5-4-3-2-1-0-enter) to start the update. Let the update finish, and when the unit reboots, you should be back in business.
  • Microphone doesn’t work – make sure it’s SECURELY plugged into the MediaLink cable and make sure the MediaLink cable is plugged all the way in – this cable is kind of hard to plug all the way into the radio and is one of the first to come unplugged when you bolt in the deck if it’s not plugged all the way in and “locked”
  • iPod or USB sources don’t work – make sure the MediaLink cable is plugged all the way in
  • XM has no audio – make sure the short male and female RCA jacks on the main power harness and MediaLink cable are plugged together
  • Random weird issues with display – MAKE SURE you moved all the cables out of the way behind the radio so it sits flush on the dash without pressure – you should be able to tighten the radio screws by hand – DO NOT cinch it down to “force” it into the hole. Take your time to find a home for all the cables
  • DVD/CD goes in halfway then gets ejected – remove the two shipping screws on the top of the deck – they are there to stabilize the DVD drive during shipping and must be removed prior to installation.
  • Factory controls (SW, rear console) don’t work as expected – do a “System Reset” before attempting to test any functions – this tells the deck what vehicle its in and allows it to work correctly in that vehicle
  • Blinkers/chimes are way too loud – you have a Bose vehicle and didn’t set the deck to the factory amp mode – Hit Setup>Info and tap the “th” in the word BLUETOOTH, then choose “Factory amp – ON”, then hit “Menu’ and shut off the vehicle for 30 seconds
  • iPod video doesn’t play to rear monitor – it’s not supposed to – the Advent will only play DVD to rear monitor(s)
  • Rear camera doesn’t work – Check the RCA is still plugged into the back of the radio AND the camera. Check power to the camera at the camera.
  • XM occasionally won’t report – This is a known issue when using the factory tuner. What’s going on with XM is that the XM radio and the navigation system boot up at different rates. If you pause at any point during cranking to start the motor – like pausing at the ACC or IGN positions for any period of time prior to cranking the motor (or even just the cranking process itself if the timing is just right), this is generally what causes the issue.When it occurs, the XM radio will continue to boot up during cranking, while the Advent radio gets forced back to square one to boot up all over again once the vehicle has started. What happens then is that since the XM radio has already booted up, it is now waiting for a handshake from the deck, only the deck is now going through its own bootup process. Now once the deck has booted up and is waiting for the handshake from the XM radio, the XM has already timed out and is no longer in a position to pass the correct data to the radio.If you get this situation once the radio has already booted up and you’re driving down the road, you can go into the setup menu to the second page and do a system reset while you are driving, which will force a reboot and it will re-recognize the XM radio. Or just change the color of your buttons from blue to orange or vice-versa and this will force a reboot of the radio as well.If you want to solve it once and for all, it would require buying the aftermarket XM tuner (PN#’s CNP2000UCA & CNPJEN1) and hooking it directly to the Advent unit.

BLUETOOTH TROUBLESHOOTING TIPS:

The thing to remember is a good Bluetooth connection depends on the device as much as the head unit, and because the device is created to do a lot of things at once, there are many variables that can affect signal quality. Here are some basic troubleshooting steps:
  • For intermittent connectivity issues, clear or “kill” all open apps on their phone. You may not realize that apps you opened a week ago can still be open and taking up memory and processing power. Get in the habit of doing this at least once per day.
  • Clear the phone’s cache, then soft-reset the phone by powering it off for 2-3 minutes and turning it back on. (If applicable, remove the battery.) This allows the memory to clear and any stubborn processes to stop.
  • Be sure your unit and the phone is utilizing the latest software version.
  • Verify that the phone is capable of performing the requested features. Some phone models may not include the proper protocols to perform certain functions, such as audio control or phonebook upload.
  • If all else fails, delete the pairing relationship on both devices, then re-pair. With the radio off, remove the radio’s profile from the phone by selecting “Unpair,” then do a soft-reset. Do the same on the radio; however, make sure the radio is on for 10-15 minutes before beginning the deletion process.
