The Axxess GMOS-LAN-04 GM radio replacement interface lets you replace the factory radio in select OnStar-equipped 2006-up GM vehicles using the existing wiring and connectors. Even if you don't subscribe to OnStar, you'll need this adapter to connect an aftermarket stereo.
Connect the GMOS-LAN-04 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.
You can adjust volume settings for OnStar as well as the safety chimes. In addition, this interface lets your new receiver work with your vehicle's factory amplifiers. This interface 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 works with select 2006-and up General Motors 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.
Fairly straight forward to install, did have some issues with the harness not being compatible with the steering wheel control module
Pros: Easy to install Retained most chimes and waning bells Volume feature for the radio and bells worked great
Cons: Had to rewire some of the connections to get the steering wheel controls to work properly Lost my turn signal and hazards sounds
is easy to install , nice plug and play and it works the first time .
Pros: plug and play , good quality
Cons: the price is a little high but he works good .
Amazingly easy to install
Colored wires matched, quick and simple install. All factory items still work.
I used it in my Malibu 2009 LTZ. I installed a Pioneer AVIC-120bt. Easy hook up. No Problems at all. I still have OnStar. All factory chimes
Pros: Plug & Play
A must if you want to easily keep On star, and warning chimes on an aftermarket HU. The blinker tone should have been built in instead of using a bulky relay to make the clicking sound. It serves the purpose, but is overpriced in my opinion for what you are getting.
Pros: Lets you keep warning chimes and On star
Cons: Relay used foe the blinker sound takes up precious space
Does its job. Keeps the chimes active with out the stock receiver
Pros: Everything works fine.
Would not permit higher volume levels from my wife's 2008 Chevy Malibu without significant distortion, even after swapping out original unit with another Crutchfield-supplied unit. Pretty sure the radio's not at fault, it works at lower levels.
Review revised 5/9/12
After much troubleshooting and pulling-out-of-hair, culminating in an "aha!" conversation with Crutchfield tech support, discovered that my wife's car radio does not incorporate an external audio amp. Therefore, this interface would not work. Crutchfield promptly shipped the correct interface (GMOS-LAN-03) which worked as advertised.
Pros: Can't think of anything positive to say except that I could be wrong about this product.
Cons: There's a zillion wires you have to get to fit under the dash. Case does not allow one of the plugs to go in without trimming the plastic - the opening didn't allow space for the locking tab on the wire plug-in. As mentioned, apparently not a good impedance match between OEM internal amp and aftermarket radio.
The only place where I will agree with the previous rater is that this device
does not allow aftermarket amps to be used.
Blame GM for their audio design, not Metra for their adaptation. If you are
dead-set on aftermarket amps, speakers, and head unit, then you need to be
prepared to give up the factory XM, OnStar, and warning chimes, or to do a lot
of work to re-engineer the GM system. This issue is not unique to GM vehicles -
many modern automobiles have highly integrated audio systems and it is getting
much more difficult to install aftermarket equipment!
I used this interface to replace my Monsoon (Panasonic) radio that had failed
buttons, with a JVC unit, in my 2007 Saturn Sky. It worked almost flawlessly.
The one issue: if you like leaving your key in the ignition with the door open,
the chime WILL time out, unlike the factory setup. I will have to remember to
take my key out when I am fueling my car....
This unit will only work if you replace your stereo, and still use your original speaker setup, amp'd by the stereo.
If you try to use an external amp, you'll loose all the features of this interface, and it will become worthless.
Read a lot and get clear of what will your setup be.
Overview: The GMOS-LAN-04 is designed to retain the amplified sound system, Onstar's emergency services function, and the warning chimes that are normally lost when the OEM radio is removed and an aftermarket radio is installed in select GM vehicles. It also provides a 12 volt accessory output for proper aftermarket radio operation. In addition, the GMOS-LAN-04 provides a mute, parking brake, VSS or speed sense, and a reverse output to make installing an aftermarket navigation radio simpler and less time consuming.
Compatibility:The GMOS-LAN-04 is compatible with the following GM vehicles:
Volume Adjustment: The GMOS-LAN-04 interface features potentiometer located on the 16 pin harness side of the module to adjust the volume, including chime and audible turn signal indicator volume.
OEM Steering Wheel Control Compatible (optional): The GMOS-LAN-04 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 (item number 120ASWC1, sold separately).
Connections: The GMOS-LAN-04 consists of a single interface with a 16-pin connector on one end and an 18-pin connector on the other end, along with the corresponding harnesses. The 16-pin harness plugs into the interface and is hardwired to your new radio's harness. The 18-pin harness plugs into the interface and three OEM harnesses behind the radio. The 18-pin harness also has several leads to hardwire to the new radio.
Installation Note: The GMOS-LAN-04 uses the existing factory amp to send the audio from the OnStar, door chime and turn signal sound to the left front speaker of your vehicle. So you will need to retain at least the front channels of your factory amp to utilize this interface.
Optional RSE Retention Harness: The Metra GMRSAV (120GMRSAV, sold separately) is an RSE retention harness designed to retain the rear seat entertainment system in these select GM vehicles. The GMRSAV provides an audio/video input to the factory overhead video screen from your new aftermarket radio, and provides the audio/video output from the rear seat control panel to the aftermarket head unit.
