For sale is this head unit in great shape and working order. Screen is without blemish. I bought this to upgrade my Chevrolet truck radio for a back up camera and nav capabilities. Never got to do it and need some cash. These units must be brought to the dealer to program. Also check the part number with your dealer to make sure that this unit will work with your vehicle. This unit retails for $2,500.00 from the dealer. It's a great addition to any vehicle. If you've ever used one you know how nice they are. Also hands down the best this for hitching up. Get this one at a fraction of the price. Check my other auctions, I have for sale a camera kit for a GM truck tailgate. Bid confidently. Guaranteed not DOA.
