Well, I've decided to go for the Nav retrofit, I've got almost everything lined up and I'm getting ready to make the harness, but the RCCM is holding me up. Like almost everyone who does this mod it is the one part that is hard to fine. I think I found one but I need a part number to be sure. Does anyone have the part number for the remote climate control module? I haven't ahd teh chance to check with the dealship yet but even they can get it wrong with parts! Any help is appriciated.
