Your post is very useful but know that I´m going to order my e91 I´m thinking in buying my alarm+PDC after market...
I´ve 2 questions:the alarm kit I saw here http://www.realoem.com/bmw/showparts...87&hg=65&fg=60
does not have all the peaces you have at your first picture.However, the your kit number is the same as at this link?
Do you think that rear PDC does already have electric installation such as the alarm?
Waiting for your reply
