I bought this interface and have since sold the vehicle. This Product retails around$150.00. It has never been installed. The label has a "B" on the end (GMAH24B). It is not a B (mislabled from the factory).

GMAH24
Now you can replace the factory radio in your OnStar equipped GM vehicle and maintain all of the OnStar functionality. The GMAH24 plugs into the connectors in the dash and provides wiring for an aftermarket receiver. It includes on-board switching and amplification to provide OnStar signals through the front two speakers while automatically muting the aftermarket receiver. The GMAH24 plugs into the factory Molex (rectangular) connectors and provides power, ground, and speaker leads. It even reports a "healthy status" to the vehicle’s data bus, and retains the RAP (retained accessory power) that automatically turns off your new radio when you exit the vehicle. Not compatible with Bose systems. Bose equipped vehicles require the GMAH24B, available separately. The GMAH24 can be used with Bose systems only when replacing the factory Bose amplifiers and speakers.
