How do you remove BMW rear view mirror?

Just did it in my 2004 330Ci. Not sure what version of mirror you have. Mine had alarm red strobe and "SOS" button, electrochromatic. The mirror mounts onto one post near the top of the window. Follow this link, look down the thread for the instructions. Works great. http://www.m5board.com/vbulletin/e39-m5-e52-z8-discussion/111088-update-number-disconnected-defective-mirrors-no-reply-magna-donnelly-3.html

Good luck Iggy
