2004 Head unit. Doing an aftermarket upgrade so this has to go. Worked well, but does have a vertical line of dead pixels at the spot where, if you were looking at the left-right balance in the fader options menu, the right side vertical line would be invisible (unless you adjusted it). Not a good description, but that's the best way I can describe. I guess you could say that the line is 10-20 pixels to the right of center; it's one pixel width. Otherwise, worked fine. Does not play mp3s as far as I know. $25 and you pay shipping.
