My 2010 335i E90 LCI came with Premium package and Comfort Access, no prewire.
My mirror has autodim, compass and Universal Remote Control. I was able to verify the part number on my mirror (Part no. 51-16-9-192-321). It looks like BMW made the clown nose smaller.
My motion sensor cover doesn't have the slits so I had to replace the whole unit. The cover is attached to the rear reading light fixture and is one part and doesn't come separate. Part no 61-31-9-201-645 is for alarm motion sensor cover and lighting option (black).
I will be getting the cover this Friday and will start the installation on Saturday. Wish me luck.
