About the Metra GMOS-01 Wiring Interface
Metra's GMOS-01 interface lets you replace the factory radio in select OnStar-equipped 2000-up 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.
Hook the GMOS-01 to your aftermarket radio, mount the module, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. And you can adjust volume settings for OnStar as well as the safety chimes. 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 interface is compatible with select 2000-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: The GMOS-01 will not work with factory-installed Bose car audio systems.

OnStar & Chime Retention: The GMOS-01 retains your vehicle's OnStar Emergency Services feature and the factory chime that warns the door is open. The volume is adjustable for both the OnStar output and the warning chime.
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-01 is designed to retain this feature.
NAV Outputs: The GMOS-05 also provides Parking Brake, VSS (Vehicle Speed Sensor), and a Reverse Output to make installing an aftermarket Navigation radio simpler and less time consuming.
OEM Steering Wheel Control Compatible (optional): The GMOS-01 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).
