I have a JVC KV-AVX2 that I pulled from my car to change to something more practical for my uses. It is a single DIN. The deck works perfectly. internal amp was maybe used for a few weeks only, as I have separate amps for the speakers and subs. it has a 3.5 in LCD screen that plays DVD, divx and more. will play DVD-MP3 CD's. there is a back up cam function (need camera). I was going to rig it up with a camera on the back of a trailer to see what was behind the trailer backing up (i just don't have the truck or trailer yet). I have used it for a little less than a year and a half. you can snag this on eBay still for $400 new. Id like to get $200+ shipping. I am located in Oregon, in the Portland area.
