I wanted to know if anyone knows which pioneer cd decks are compatible with an '04 Grand Am. BestBuy's website says none in it's stores will fit yet Circuit City has one that is suppose to. It's a Pioneer AVH-P5700DVD. BestBuy has it but says it's not compatible. I am just browsing right now though and plan on changing it probably in a few months to a year. I like the AVH-P6800DVD model, but I am not sure if that will work for my car. If anyone can help me out please do. I really appreciate any help I can get to make a decision on what to buy. Thank you.
