I have an appointment on 17 Dec for an inspection so see if it is pre-wired (Germans have procedures they have to go threw before they even look at your car). I plan on gettign the kit installed and will keep you posted.
Does your car have Comfort Access? if not, you'll also need the Auxiliary Cable (T) from the instruction sheet. Can you possibly get me the part number for the Auxiliary cable from your dealer?
