About the Axxess GMOS-LAN-02 Wiring Interface

The Axxess GMOS-LAN-02 GM radio replacement interface lets you replace the factory radio in select OnStar® equipped 2006-up General Motors vehicles using the existing wiring and connectors. Even if you don't subscribe to OnStar, you'll need this interface to connect an aftermarket stereo.

The Axxess GMOS-LAN-02 GM radio replacement interface lets you replace the factory radio in select OnStar® equipped 2006-up General Motors vehicles using the existing wiring and connectors. Even if you don't subscribe to OnStar, you'll need this interface to connect an aftermarket stereo.

Connect the GMOS-LAN-02 to your aftermarket radio, mount the module, and plug it into the existing factory plug. Get the great sound you want, and keep all of the important safety features intact, including your factory Bluetooth and your GM backup camera. And you can adjust volume settings for OnStar as well as the safety chimes. In addition, this harness lets your new receiver work with any existing factory amplifiers.

Also, once you turn off the ignition in these GM vehicles, the radio continues to play until you open the door. This interface maintains that function with your new aftermarket radio. This adapter gives you convenient plug-in connections for the Axxess steering wheel control adapter (not included) that works with most aftermarket stereos – that means less wiring work for you.

This interface is compatible with select 2006-and up GM vehicles. If you haven't done so already, please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this item is compatible with your vehicle. Warranty: 1 year.

My radio has 4 connectors and the harness that sales person said would work for my car only has 2 so it doesn't work. Wasted my money.

2007 GMC Yukon XL Denali

Verified customer (What's this?)
Verified employee purchase (What's this?)

Had to use this 1 since Crutchfield doesn't offer the pac kit for my 07 denali. I will say that the directions are incomplete, so if your not a self taught expert I deff wouldn't recommend doing it yourself. Many wires in the harness were left out. I had to go at it twice just to get the Bose to kick on. I can honestly say I'll never buy an axxess again.

Pros: Kept what I needed to keep.

Cons: Pain in the ass. Harness is bulky as all hell. Not a pac.

Crutchfield customer from Montgomery, AL on 12/13/2016

2007 Chevrolet Tahoe

Verified customer (What's this?)
Verified employee purchase (What's this?)

The adapter is great, the instructions are worthless. I haven't installed a car stereo in 20 years but I used to be pretty good at it. My son wanted to put a new stereo in his car but couldn't afford both the stereo and the installation cost so I offered to help him install his new stereo. It took one call to the Crutchfield help team and another to the Axxess help desk but we finally got everything installed. The two help desks differed on the instructions for the steering wheel remote instructions so that is still not functioning but hopefully I can make another call to the help desk this week to finish the install. Otherwise, the Axxess kit made the install very quick and easy. You just need to be a little creative to stuff the installation kit into the dash behind the stereo.

Pros: Very easy install once you get past the instructions. If you know enough about stereos you can easily install yourself.

Cons: The worst instructions I have ever encountered. If you don't know the basics, don't try to install this on your own.

Installed this in my 2013 Impala LTZ. Worked exactly as advertised. Really made the install a breeze. Allowed me to adjust the gain to the Bose amp, a definite plus, and i was able to tone down the warning chimes to almost inaudible. All in all, a great product.

Go with the PAC model instead

chris9510 from St Louis on 5/4/2010

2007 GMC Yukon XL

Verified customer (What's this?)
Verified employee purchase (What's this?)

like many other reviewers, I too was recommended this kit. This kit works, don't get us wrong, but if you have a factory LCD/DVD forget the wireless headphones. The control module is huge and hard to hide inside the dash. Bought the PAC GMRVD to retain factory LCD, rear seat controls, and IR (wireless headphones), but needs the PAC OS-3/OS-3BOSE or better to make the IR work. Bought the PAC OS-4 since the 3 series were discontinued. Much smaller than the Axxess, fixed IR issues, better chime system, easier to tuck into the dash, better all around. PAC model also comes with pre-wired harness for a steering wheel controls like the SWI-PS!! Stay away from this if you have a factory LCD and want to retain its function, otherwise it works as advertised.

Needs a major improvement

Kerry from Ft Worth, TX on 3/23/2009

2008 Chevrolet Silverado

Verified customer (What's this?)
Verified employee purchase (What's this?)

My installation: 2008 Silverado, Kenwood DNX-5120, factory Bose amp. (Truck came with standard MP3 radio, no nav.) Swapped this out for a PAC OS-4 While the GMOS-LAN-02 DID work, it had two major flaws. 1. The steering wheel controls do not operate the Onstar. 2. The dealbreaker is that even though the unit includes a mute wire and the DNX5120 has a mute function, using the Onstar kills power to the radio instead of simply muting or pausing the audio. While this may be OK for a regular radio, I find it unacceptable for a navigation unit with its longer bootup time. There is a workaround involving splicing in a 10k resistor between the brown mute and the red switched power wires, but this causes the DNX5120 to be in "attenuate" mode whenever the truck is started. Minor quibbles: 1. I did not like that when you initiate a call with the Onstar, the Metra takes long enough to switch over that the "Onstar Ready" prompt is not heard. It's actually ready, you just have to assume and proceed with the call. 2. The turn signals sound like someone tapping a fingernail on the windshield, not nearly as nice as the factory sound or the replacement.

Not Best Suited for 2007 Suburban

George from Miami, FL on 11/3/2008

Verified customer (What's this?)
Verified employee purchase (What's this?)

This product was suggested for the 2007 Suburban but it looses the functionality of the rear seat entertainment system. This includes the controls of the rear center console, rear video, and rear IR-headphones. The solution was the PAC OS-3Bose, sent to me as a replacement by Crutchfield, and everything works like a charm. All rear controls work, as well as the video-audio in, IR-headphones, and Video. The OS-3Bose has to be used in conjunction with the PAC GMRVD and PAC SWI-JACK. BTW, I replaced the original head unit with the Kenwood DDX712.

A surprising help

Matthew from Michigan on 9/10/2008

2006 Chevrolet Impala

Verified customer (What's this?)
Verified employee purchase (What's this?)

When Crutchfield first recommended The GM Adapter to keep my door ajar chimes and blinker clicking sounds, I thought, "that's a lot of money for a couple of cheesy warning noises", and was not going to get it. But they said it also had some other hookups and kept the OnStar option, so I reluctantly ponied up the money. Boy, was I glad I did. It made hooking up my Pioneer harness to my Chevy Impala 1000% easier. It had all the hookups right there: Parking brake, back up lights, VSS, illumination, ground, power and RCA's for all speakers and amps. No long leads back to the trunk! No splicing into wires! No bad grounds! And now, all the chimes and buzzers have an adjustable volume, too. It made it so much more of a professional install.

Features

GMOS-LAN-02 Radio Replacement Interface: The GMOS-LAN-02 radio replacement interface module allows the replacement of the factory radio in your 2006-up GM LAN 29 amplified vehicle with an aftermarket head unit. This interface module allows you to retain factory features such as OnStar, Bluetooth, steering wheel control (optional interface required), and warning chimes. The interface module also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.

  • Retained Accessory Power (R.A.P.): The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The GMOS-LAN-02 is designed to retain this feature.
  • OnStar Compatible: The GMOS-LAN-02 is designed to retain the factory OnStar emergency services system that would normally be lost when your factory radio is replaced by an aftermarket head unit.
  • Bluetooth: The GMOS-LAN-02 radio replacement interface module retains your factory Bluetooth functionality.
  • Warning Chimes: The GMOS-LAN-02 OEM integration kit retains your vehicle's factory warning chimes.
  • Backup Camera: The GMOS-LAN-02 includes a composite video harness which allows you to retain your vehicle's factory backup camera.
  • OEM Steering Wheel Control Compatible (optional): The GMOS-LAN-02 features a right-angle 3.5mm connector that lets you keep your GM vehicle's OEM steering wheel controls via the optional Axxess Steering Wheel Control Interface (120ASWC1, sold separately).

Vehicle Compatibility: The GMOS-LAN-02 is compatible with select 2006-up GM LAN 29 vehicles that feature a factory amplified sound system (as of 9/30/2013).

Adjustable Volume for Chimes/OnStar: The GMOS-LAN-02 interface features potentiometer located on the 10 pin harness of the module, to adjust the chime/OnStar volume of your vehicle. Rotate clockwise to make the chime/OnStar louder and counterclockwise to make the chime/OnStar softer.

Connections: The GMOS-LAN-02 consists of a single interface module with a 18-pin connector on one end and a 16-pin connector on the other end. It also includes three harnesses and an antenna adapter. One harness includes a 16-pin plug that plugs into the 16-pin connection on the interface and its bare lead wires are hardwired into your new radio's harness. The other harness includes a 18-pin plug that plugs into the 18-pin connection of the interface and includes GM factory plugs that plug into the factory side plugs behind the radio. It also includes bare power/ground wires that will need to be hardwired into your new radio's harness. In addition there is a composite video harness to retain your vehicle's factory backup camera.
