Anyone have experience swapping out the head unit with an aftermarket unit? I have the entertainment system w/ dvd player in the back on the roof of the vehicle and the rear radio/audio controls on the back of the center console. I want to keep as much functionality as I can without having to just buy another stock unit. for the same price I can get a better up-to-date radio w/ sat radio and touch screen nav.. I'd rather do that. Wondering what brands/models will work
