I bought this unit from ebay for $170ish shipped. It's a 8.5" LCD screen with built-in DVD player, MP3/MP4 decorder,AV-in/out, FM out (plays audio thru factory stereo), USB input, SD/RAM card reader, and a remote control. I am very impressed with the unit. Installation was a breeze. Took me only 30 minutes to install and wires are out of sight for a nice OEM fit and finish.
