M3 mirror Homelink question
 

if i was to just buy a mirror for my m3 with the home link function and plug it in would everything work?

would the home link work as its suppose to or would i have to program it......

also do i need a Rain light sensor plug also because my car doesnt have one!

Follow the below link. Yeah, it's for e9x mirror, but it should be pretty close, if not exaxt, to what you want to do.
