Taking delivery on my M3P on Thursday and realized it doesn't come with Homelink. I was about to order it but was seeing threads from people saying they couldn't get it to work. I have successfully programmed my current and past cars (Mercedes-Benz and Porsche) and have been using the buttons on the mirrors of those cars to operate my garage with no problems. I believe Homelink is the only company that offers this technology unless I am mistaken, so I am assuming if it works with my MB and Porsche, then my Tesla should also work, am I right? Sorry to sound cheap, but I would be slightly annoyed if I had it installed in the Tesla only to find out afterwards that it's useless.
