You want to install a new car stereo in your 2000-up GM vehicle, but you don't want to lose useful factory functions. Thanks to the Axxess AX-ADGM100 interface, you can upgrade to the higher sound quality of an aftermarket receiver while maintaining your factory-installed separate satellite radio tuner, OnStar®, Bluetooth®, factory amplifier, and the Retained Accessory Power (RAP). In some vehicles, you can also retain your factory rear seat entertainment system and your GM backup camera.
All harnesses are included, and this interface works with all amplified and non-amplified GM factory systems. The Axxess AX-ADGM100 interface also includes a direct connection for the Axxess ASWC-1 steering wheel control interface (sold separately), so you can keep your factory steering wheel controls when you install your new car stereo.
The package includes the Axxess AX-ADGM100 module, the GMLAN29 harness, the GMLAN11 harness, and the CLASS II harness. If your vehicle uses the GMLAN29 harness, the package also includes the16-pin backup camera harness and the 16-pin rear-seat entertainment system harness needed to retain those features (see the Details tab for compatibility chart).Important Installation Note: If you plan on keeping the GM satellite radio tuner and your GM vehicle does not have a Driver Information Center screen, you'll need to buy a separate dash-mount screen to display satellite radio and iPod info. Your new car stereo must have a rear RCA auxiliary input.
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.
For a adapter harness there is a lot of cutting and splicing of wires. The instruction are horrible. I had to call several times for terminology explanations and explanations on the instructions themselves.
Pros: Not much
Cons: Bad and misleading instructions
The product seems like it does everything it's intended to do. The Sirius part is misleading and will not display the satellite information on your aftermarket head unit. ( It does say this in the instructions and website so it's partly my fault because i didn't read before I bought.) The kit comes with 3 different harnesses. It would be cheaper if they only sent you only the harness that you needed.
Pros: Does what it's intended to do. Easy to connect everything if you read the instructions.
Cons: More harnesses than what is needed. Hard to get all of the wires in the radio compartment.
So simple to connect!
Pros: Easy connection to make
Confusing instructions for my application. I figured it out, but wasnt quite clear. Dimmer circuit doesnt wirk as advertised following wiring instructions. Havent had time to consult tech support yet. otherwise worked well.
Pros: Everything needed for various models of my vehicle.
Cons: Confusing instructions due to various vehicle options.
easy to install but the chime part of the module dosent work
Cons:Crutchfield response on April 2, 2014 Our tech support team contacted the customer to offer to exchange the unit for a working one.
Totally useless......it's very bulky and nearly just fits in the truck....doesn't work on series 2 tahoes
Cons: To much work to try to make it work....huuuuu
I'm not going to say it was a walk in the park to install. The instructions have to be followed closely and you will have success. The tech guys at Crutchfield are awesome and can provide the help you have to any questions that may arise during your installation.
Pros: It just works. Makes your installation something you can be proud of.
Cons: You have to be thorough in following the instructions. Cant short cut.
When I selected a radio there were 2 different wiring harness that came up as options. one look like you need to splice a lot and the other looked like it had a boat load of connectors. More connectors, easier install right? NO WAY. This AX-ADGM100 came with three different harnesses, all needed splicing! I only used one of them, so you pay for stuff you don't need. You are splicing wires, so save yourself some cash and get the other one.
Pros: Connectors fit nice and radio splicing was consistent: red/red, blue/blue, blue-pink/blue-pink, etc, etc. Crutchfield tech support is AWESOME!!!!
Cons: Way too much in the box. Three different harnesses made me spend a half hour trying to figure out which one would work best. Big harness, hard to cram it all in dash. Instructions SUCK! I suggest reading the whole thing, even the part that you think doesn't apply. There is info there you need. No pictures to identify what stuff is.
Great product but alot of extra plugs and harness's were left over seems they could eliminate some of them and lower the price instead of trying to make one unit work for every car.
Cons: The directions arent very clear on certain things but they do have a good phone tech support.
I have electronics training from the USMC, so thought I could handle this. The directions do not match the labels on the harnesses in the kit, so I had to call Crutchfield to figure out which harness to use. The price was exorbitant for what this kit does, but I needed it to retain all the functions my truck came with - and it even didn't succeed in that. The smart box that is supposed to recognize your vehicle didn't - we had to fight with it for 2 hours or more, then finally call Crutchfield to get them involved before we finally got it to work. Even so, the rear entertainment zone still doesn't work. I wound up with more unused stuff than I used - the price could come way down if they just supplied application-specific kit instead of one-size-attempts-to-fit-all. And the directions are not written for a layman - I had to call to get several terms explained so I could figure out which wires went where. And finally, there is only limited space inside the dash, and this kit was bulky with a LOT of excess wire and a real pain to get it all crammed in there.
Pros: Crutchfield support was great and the only reason they did not get the whole order back.
Cons: Instructions refer to part numbers which are NOWHERE except in the directions. You would think they would correct the directions to refer to the part numbers marked on the parts. The kit includes several surplus harnesses, so if you move your head unit around between numerous vehicles, you're set. Otherwise, you wind up with a lot of expensive unused scrap.
Overkill for most applications. Get the GMOS-4 for 2000 up GM's
Pros: None for me.
Cons: Horrible and incorrect instructions. 3 harnesses that are not identified for their application.
unable to get this to work right.
Cons: not working like it shouldCrutchfield response on December 23, 2013 We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.
For my 2003 Suburban this worked ok. The harness itself integrated well but I now own 2 other harnesses and a nav harness because it all comes in the same package. Instructions are definitely designed for a professional installer. Or maybe I am the only one who doesn't know what a 22 way or 24 way connector looks like. Could be labeled a little better. The GM harness comes with adapters for GM vehicles after 2003. So if I ever purchase a newer model vehicle I could install my stereo in it. For the money the synthesized chimes for the doors and leaving the keys in the car could be better. It said I could keep factory XM and my rear entertainment system, well the rear entertainment system works but initially had the XM channel playing through the headphones. The fix was to disconnect the XM. No big deal for us since we didn't ever use it. Connection once I figured out which bag of wires went to my vehicle was very simple. Had to adjust the chime volume on the module box down to its lowest setting. It does some weird clicks and hums to transition on the chimes but is not as noticeable as it was when we hooked it up.
Pros: Easy connection after splicing some wires
Cons: Poorly labeled wire harness bags, synthesized chime sounds, couldn't keep XM for my car even though I should have been able to
Recommended adapter by the advisor.
Pros: Worked on my new stereo for the most part..
Cons: price, too many wires to splice, didn't work for the steering wheel controls or factory sat radio on my 2005 GMC Sierra. There has to be a easier way to hook up your new stereo.
It allowed me to add my Pioneer avh-4500bt head unit to my car while retaining the factory Bose system, all the normal lock and unlock chimes, the Onstar diagnostic system, and the Aux. power. Aux. Power is what allows the radio to play after you take the key out of the ignition and then turn off after you open a car door. I had professional installation on my system, so ease of installation I can't comment on.
Pros: Worked Perfectly
Cons: None so far.
The interface on this harness was touch-n-go. The chimes worked intermittently and did not provide the rear control functionality. Crutchfield tech support was great when the issue arose and sent a replacement, however still did not provide chimes consistantly. Ended up using the GMOS-04 for the Bose system in my 04 Tahoe.
All-In-One GM Replacement Interface Solution: The Axxess AX-ADGM100 is an all-in-one solution to add an aftermarket radio to select 2000-up GM vehicles with the CLASS II, GM LAN 11, or GM LAN 29 bit data systems. The AX-ADGM100 can be used in vehicles with or without factory amplifiers, including digital amplified systems. The AX-ADGM100 is able to retain OnStar, Bluetooth, Satellite Radio (factory D.I.C. or optional LCD required), steering wheel controls (requires optional adapter), rear-seat entertainment (GM LAN 29 harness only; depending on type of vehicle), and factory backup camera (GM LAN 29 harness only; depending on type of vehicle). In addition, all the warning chimes and convenience features are retained that are normally lost when the OEM radio is removed. The AX-ADGM100 also provides a 12-volt/10-amp accessory output and connections to help install a navigation radio which include VSS, Parking Brake, and Reverse (rear-view camera). Common features include:
Note: There are three types of GM harness included (CLASS II, GM LAN 11 bit, and GM LAN 29 bit). Only one will be used for your specific vehicle. Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible and what additional accessories will be needed.

Satellite Radio Note: Your factory Satellite Radio information will continue to be displayed through your vehicle's factory Driver Information Center (D.I.C.). This factory D.I.C. is not removed when replacing your factory radio with your new aftermarket head unit. If your vehicle is not equipped with a separate Driver Information Center and the factory radio displays all Satellite Radio information, you will lose Satellite Radio text, unless you purchase the XIA-LCD (120XIALCD, sold separately), which provides a separate LCD screen from your new aftermarket stereo and allows you to navigate through factory installed Satellite Radio options.
Note: Vehicles that require the GM LAN 29 harness still allow you to control your factory Satellite Radio through your vehicle's factory steering wheel controls, even without the Driver Information Center; but you will lose text display.
16-Pin Harness Color Codes: In addition to the three vehicle specific harnesses, the Axxess AX-ADGM100 includes a 16-pin harness which connects between the interface module and your aftermarket receiver. These connections will need to be crimped or soldered together.
