Nick,
Important safety tip here... open the ashtray and cupholders before removing the faceplate. The faceplate has metal spring clips in the back of it, and they will scratch on the face of the ashtray and cupholders while you're disconnecting the wires from it. I had my dealer install the RB1 Nav system, and I couldn't figure out where all the scratches on my ashtray came from. When I went to do some more wiring myself, it was pretty obvious.
