If you wanna retain the OnStar you will need a PAC OS-1. This will allow the use of an aftermarket radio with your OnStar. You can also add amps if you want. If at all possible choose an aftermarket radio with a mute wire. The interface will work with radios with or without the mute wire, but it works better with.
