I not sure but i thought there was a 6disk cd changer that you could get with the mach460 I want to put a changer in my car but i want to keep my stock radio because aftermarket radios just dont look right in the car stock looks best to me and i want a changer tired of the single cd i want one that will just plug in to the factory radio no r/f modular crap. will another ford changer plug in to it? Where can i get one from?
