Well I finally got the car and now its time for the Alarm. How is these alarm on the 3 seriers? The dealer did not have one on a 3 seriers but had one on a X5. Does it have that peizo arm and disarm sound? I assume no shock protection only glass breakage?

Also the salesman said you can program the LED under the mirrow to come on when the doors are locked. Can I program this myself?
