I had the same issue and went with a Kenwood unit. Not to advertise, but I had mine installed at BestBuy. They had all the harnesses and trim pieces. Stop by there and ask one of the guys in the Car Audio department. Sorry I dont have the actual part number with me right now, IIRC it was less than $80 for the harness adaptor.
