I bought a radio for my other vehicle off a buddy, this was on it, I have no use for it. Is only about 6 months old, worked fine when he pulled it. About 4 inches of wire left on both side (he had them all twisted/taped so I cut off the mess)
From the website: Allows installation of an aftermarket radio using the existing factory wiring and connectors
For non-amplified systems Retains warning chimes with adjustable volume Retains RAP Includes Navigation outputs Retains OnStar with adjustable volume Can also be used to retain OnStar/Chimes when bypassing a factory amplified system The GMOS-01 interface is designed to allow the user to replace the OEM radio with an aftermarket unit in non-amplified GM vehicles and retain full functionality of the Onstar system as well as all safety and warning chimes. The GMOS-01 will also retain the retained accessory power convenience features. This interface has the capability of adjusting chime and Onstar volumes as well. In addition to these features, the GMOS-01 now has the required outputs for the installation of a navigation radio
These are going for like 85 new... not sure what it's really worth, 50 shipped?, I'm open for offers
