The Axxess GMOS-044 GM interface lets you replace the factory radio in select OnStar-equipped 2010-16 GM 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-044 GM interface lets you replace the factory radio in select OnStar-equipped 2010-16 GM 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-044 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. 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 is compatible with select 2011-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.

Features

Radio Replacement Interface: The GMOS-044 lets you replace the factory radio in select GM vehicles with an aftermarket head unit. It works in both amplified and non-amplified factory audio systems and is designed to retain OnStar and the warning chimes that are normally lost when the OEM radio is removed. It also provides a 12-volt accessory output for aftermarket radio operation. Additionally, the GMOS-044 provides a Mute, Parking Brake, VSS (speed sense), and Reverse outputs to make installing an aftermarket navigation unit less time consuming.

Vehicle Compatibility: The GMOS-044 works in select GM vehicles with monochrome screen; including the 2011-2015 Chevy Cruze and 2016 Chevy Cruze Limited.

OEM Steering Wheel Control Compatible (optional): The GMOS-044 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).

Note: The GM vehicle must have factory steering wheel controls to retain access to the factory customization menu, once the factory radio is replaced with an aftermarket head unit.

OnStar & Chime Volume Adjustment: The volume is adjustable for both the OnStar output and the warning chime.

Q
Will this retain the steering controls in a 2015 chevy equinox or do I need to buy something else for that?
frankie  Aug 12, 2022
1 answer
A
If you have the 2015 Equinox with the monochrome LCD screen and your radio does have a steering wheel control input, you'll need the Axxess ASWC-1 Steering Wheel Control Adapter retain steering wheel controls https://www.crutchfield.com/p_120ASWC1/Axxess-ASWC-1-Steering-Wheel-Control-Adapter.html. You still need the Axxess GMOS-044 Wiring Interface to interface with your stock wiring harness. If your radio is not the monochrome LCD screen you will need an entirely different wiring interface. If that is the case, give us a call at 1-800-324-9695 and we'll be happy to help you find the correct wiring for your vehicle!

If you are asking about the display that shows temps and time, then yes. it works. although you need to set it from the steering wheel controls. I googled the procedure.

Q
Does it support rear parking assist sensor warning sounds?
darrell  Mar 30, 2014

A
Good question! However I am not sure if it retains the reverse warning chime. My car doesnt have that feature. I would suggest you give a call into axxess support before you buy. Their number can be found on axxessinterfaces dot com. they have much more know how on these gmos harnesses than Crutchfield support does. They can be tricky. I tried doing it myself once and it didn't work out well. Crutchfield sent me a replacement and I just broke down and had the local big box store put it in for 95 bucks. Works flawlessly now. Don't know if it was me or the first unit I had. Oh well. Good luck!
