OnStar Amplified Dock ‘N’ Lock
The GMOS-09 interface is designed to allow the user to replace the OEM radio with an aftermarket unit in amplified GM vehicles equipped with the â€œDock-n-Lockâ€ style harness and retain full functionality of the OnStar system as well as all safety and warning chimes. The GMOS-09 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-09 now has the required outputs for the installation of a navigation radio.
