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.
Note: Most vehicles will require additional installation parts please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.
30 min and was done with the soldering. If you're wanting to retain the rear camera and DVD monitor in your Suburban, you'll have to cut the plastic and metal behind the head unit.
Pros: Works and cheaper that my local car stereo dealer.
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.
Pros: Easy to wire up, adjustable amp gain and chime volume.
Fairly easy to install. No complaints, it works fine.
Pros: easy to install
It's really nice to have a product that can help you retain all your factory options
Installation was easy. Works as advertised.
Pros: Directions were easy to understand. Did it's job.
Works great easy to install and retains all factory features including backup camera, rear dvd screen, onstar, & factory cell phone
Pros: Easy to install! Works Great!
This would have been 5 star, but had problems with some kind of faulty wiring in harness that connects to the steering wheel interface adapter. Couldnt figure out why my steering wheel controls wouldnt work, then a call to Crutchfield Tech support really helped. hey, Im a 53 yr old mom with 2 kids. I was able to install this myself and get my new car stereo w bluetooth playing. Had to make some hardwiring adaptions, but it works great now. It is a great feeling!! Yeah Tech Support!!!
Module and wiring harness very easy to install.
very good integration. not exactly simple to install but with crutchfields excellent tech support, its a snap. would definitely rate this a 4 hammer install job.
It's what you need to replace your factory radio if you want to retain the on star functions with a after market radio
Pros: It gets the Job done perfectly
Cons: This price is a little High
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.
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
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
2. The turn signals sound like someone tapping a fingernail on the
windshield, not nearly as nice as the factory sound or the replacement.
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.
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.
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.
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).
Note: Please consult the Crutchfield Car Selector to see if your vehicle is compatible.
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.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Krissy Mar 07, 2015 ] Staff
