Bmw programming

[Sparksy]

Hi, I have just recently got a Chamberlain Comfort opener. I’m trying to program my car to my garage opener. I have a bmw which has the 3 buttons on the Mirror. I have done the usual set up procedure so cleared old codes. Pressed the remote button, held down and then pressed one of the buttons on the mirror to learn front the the remote key. Not learning. I have also tried to learn from the opener itself and still not learning. I can only guess that Bmw is not compatible with chamberlain or there is another way to program this. 
Any help appreciated
