How much did you have to pay for it?
I ran into trouble trying to use the camera/CCU inputs on the DCU and display. Never did make it work. I would be interested in your experience. I would recommend hooking it up before you install everything. It is a lot of wiring, especially snaking the wires through the tailgate. Did you get the tailgate harness?
