I'm picking up an '04 Cobra this weekend, and then driving it 660 miles home. This is probably a dumb question, but I couldn't find the answer by searching. I'd like to hook up my MP3 player to the stock 6-disc head unit but wasn't sure if that was possible or, if it was, what kind of cable I'd need (RCA or headphone-style). Any advice would be appreciated. Thanks!
