Scosche Stereo replacement GM interface

Scosche's GM interfaces work properly with factory systems with OnStar and standard Bose. They allow you to retain existing safety features, warning indicators and other functionality when upgrading to an aftermarket radio. They also preserve a healthy status in internal diagnostics by sending the proper data commands to your vehicle's ECM.
