METRA GMOS-01 Interface
- Calculated at Checkout
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.
