The Model X has a single USS topside. If you lower your garage door to within a for or so of the car's roof, then position the car so the top sensor is directly under the edge of the partially closed door. You should be able to trip the "remember" action message.Oh one more follow up, I could never get it to show the “remember this location” option no matter what I do…I tried holding down the door button from the screen and from the physical button, it never asks. Any ideas for this?
I had to do this in my garage because it has 12 foot tall overhead door and 14 foot ceiling. It took a bit of fiddling to get it to trip.
