So I've been browsing this forum looking for my answer and so far nothing. I pick up my new car tomorrow ('02 GP GT) and I've got my radio/amp/subs sitting here from my previous car and I'm itching to get it all in. The Grand Prix has OnStar, steering wheel controls and it has this radio :



Is this a bose stereo or not?

Where do I need to start? I have my Head unit, my amp, etc I know how to wire it all. What I'm lost about is what adapters do I need for OnStar, what adapters do I need for the steering wheel controls? If I have the bose system, would it be better to let the bose amp take care of the speakers and wire my amp for subs or what?

Thanks for the info!
