Oh really? Do you have a link or the work-order form for the retrofit?
I tried looking up online but couldn't find it. Would be much appreciated. Thanks!
Edit: I've found solutions like this http://www.bimmer-tech.net/shop/bmw-...ntrol-retrofit
that uses OEM BMW parts, but I'm looking for something like this http://www.kneb.net/bmw/E46/Park%20d...20retrofit.pdf
