Just installed this in my '82 for a cheap solution to my horrible radio. Got it off Ebay for $95 shipped. It does CD/MP3/FM3/AM/AUX in on the faceplate. I have 4x10s in the doors and 6x9s inthe rear pillars and it sounds great, almost like theres a small sub in there. I think the pressure on the speakers from a box really helps because my 4x10s sounded like crap until I got my door panels on. Anyways, I would recommend this HU to anyone that needs a nice cheap HU for their I-pod.
