Alright here is the deal I have been looking all over online trying to find out exactly what I need for a radio install I want to do. So here is the deal I have and 2007 Grad Prix and I want to do a double din radio install. Now the problem I can not find out what exactly you need for the install I'd like to keep all the factory stuff like door chimes and keep my remote start, etc. I do not want to tap into any wires there has to be some sort of a kit with a harness or something but I can't find what I am looking for anywhere if you guys could help me out that would be awesome a link where to buy everything I need for this would be sweet.
If someone could help me out that would be awesome!
Edit: I would also like to keep my steering wheel controls as well
