What Bill said. I don't remember and no longer have the invoice but figure out which headunit you want and call them. They wouldn't acknowledge that it would be plug and play but that's exactly what it was. I did manage to damage a wire connector which turned out to be the steering wheel controls but a call to them helped troubleshoot it and a new connector fixed it. My fault not theirs. The steering controls was the blue wire if that helps you at all.
