Description
GM non - amplified interface harness. Retains chimes and accessory. Works with or without onstar and provides navigation wires.
The GMOS-05 interface is designed to allow the user to replace the OEM radio with an aftermarket unit in non-amplified GM vehicles equipped with the “Dock-n-Lock” style harness and retain full functionality of the Onstar system as well as all safety and warning chimes. The GMOS-05 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-05 now has the required outputs for the installation of a navigation radio.
