When I first got our Model X, I searched for information on whether our old garage door openers were going to work with our Model X. We have very old openers, long before Homelink was invented, and before Intellicode. They are the style of openers that have 9-12 DIP switches inside the remote, and the same DIP switches on the motor in the garage. They run at 390 MHz. I think they are around 1995 vintage openers. I figured there was no chance that these DIP switch openers would work on my Model X. But these ancient openers work fine! At first, I could not get the Model X to learn the remote code. But I followed the instructions and put brand new batteries in the remote, then held the remote up to the EXACT location on the front bumper on my Model X. Seemed to take forever (about two minutes) for my Model X to learn the code, but it eventually worked. Took a few tries moving around on the bumper, and googling for the perfect spot on the bumper. So to anybody else who has old style (before Homelink) Genie garage door openers, the Tesla software and hardware WILL work with those openers. Yay! BTW - To the non-electronics types: DIP stands for Dual Inline Package. It denotes the form factor for switches that can be soldered to a circuit board.
