Traded in the 4Runner and removed the touch screen we had. This is all ready to go, no soldering required. The Maestro module lets you keep the steering wheel functionality. The head unit is in very good shape, I can't see any scratches, just a few marks on the dash kit. Should work on 2010 to 2014 depending on options. Price is $275 shipped (AK, HI additional cost).
