Metra GMOS-05 GM Class II Onstar Interface for Non-Amplified Audio systems
The GMOS-05 interface is designed to allow you to install an aftermarket radio and have it interface with the OEM vehicle and OnStar system. The GMOS-05 is designed for 2000 - 2004 GM vehicles that use the GM Class II data bus system. The interface retains full functionality of the OnStar system as well as all safety and warning chimes.
The GMOS-05 also retains the R.A.P or retained accessory power convenience feature, allowing you to use the radio after the vehicle is turned off as long as you don't open the doors. 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.
