Question:

Greetings. Will I still have to buy an interface in addition to this harness in order for the stereo to work? I'll be installing it in a 2004 Oldsmobile Bravada. It does have OnStar however I don't use it. Thanks!

    A:

    You should use this interface instead: https://www.qualitymobilevideo.com/lc-gmrc-01.html

    With this harness you will retain the door chimes and not lose other functionality of the vehicle.
