I have a 2012 X3 and about to purchase a Liftmaster 8355 garage door opener. It is compatible with Homelink V4.3 or later but there is now way to tell what version is in my X3. If it doesn't work then i would need to buy an adapter between the Homelink and the garage door opener. The only way to find out is try it to see if I can program it into the X3. Does anyone have a Liftmaster 8355 or 8550 and a 2012 or 2011 X3 with Homelink that can say it works or not?
