Hey guys... sorry for the noob questions. I have no car audio experience whatsoever so this is all new and a lot of the things I have been reading have been a little confusing. What I would like to do is replace the head unit on my 2000 Grand Prix GTP but I want to get some things clarified before I go ahead and make any purchases. I already narrowed it down to a few head units but from what I have been reading it's a little more complicated on my car due to the Bose system that's in there already. For now I don't want to replace anything else except the head unit. The Bose speakers have built in amps and I don't want to bypass those. Keeping the steering wheel controls would be nice but I know I would need an adapter for that and it would make the installation a little more complicated.
So here are some of my questions... If I install the HU, what other functions on my car would I lose? I was reading somewhere that the HUD would obviously not work but would I lose things like the door chimes? Is it really necessary to purchase an adapter to not bypass the Bose amps because I saw somewhere that I may be able to splice a wire into the HU. Is that possible? What other parts would I need besides the HU and the mounting kit? Again sorry for the noob questions... I'm really new to all of this stuff.
Left one thing out... there's no OnStar.
