Hello,What I have is a 6 disc cd changer that I took out of my 1988 GTA,it pluged right in to the back of my factory cassette player with a very long 9 pin cable that went from frt all the way back to the rear compartment.But I sold my GTA and no longer need it.So if you would like some pics please send me your email and I will send you some pics asap,and the model is ACC-40 Rampage digital audio 6 disc compact disc changer.And asfar as price?make me an offer.And by the way I controlled the cd changer with the factory radio,its pretty nice to have a cassette player and a cd changer to keep it with the factory look.thanks
