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 On Star 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 On Star volumes as well. In addition to these features, the Gmos-01 now has the required outputs for the installation of a navigation radio.
