I've been searching the web for same year and models...and I've seen them out there....so yes, it's possible... but you have to call your dealership to have them do it. Otherwise....you'll be up a creek without a paddle if you try and do it yourself.
I know FOR SURE it's possible on e65s/e66s 2004 and newer.

Call the dealership and they'll tell you how it can be done.
