Hello, I was wondering whether this head unit has a CD controller. From the tweeters and the amp(booster) in the trunk I am assuming this is a premium sound system. Is that right? If this thing has a cd controller what brand you recommend most that is compatible with the stock system that I have of course. TIA JohnD Your radio is the previous-generation Premium head unit which was replaced by the Pyramid radio in late 88 & early 89 models. Yours does not have the socket for the CD data cable, while the Pyramid does. I have one of each of these radios, but i could never get my radio to recognize my CD changer (the cable has a nick in it so i think that's the problem). I don't believe there are any aftermarket CD changers that will work with the Pyramid radio, but since both are made by Alpine maybe they make something that will work. Dunno.
