I've done my research but want to get a few things straight before I go through with the swap. When I go to the dealer to have them "marry" the 08 stereo with my 06 G6, do they need the VIN of the car the 08 stereo came from? If so, will the company I purchase the stereo from provide that for me? Will I have to request it or will they just give it to me? Thanks for your help guys as I'm excited to swap this out, but need your help.
