My son paid for this feature four weeks ago, and it's still not working! We've tried calling support a few times, but they haven't been able to help. Looks like he's going to have to take his car in for service to get this fixed. Frustrating!
I also encountered the same issue today when I went out for lunch. I tried pressing the button, but nothing happened. I was a bit worried, but when I went back out a couple of hours later, it was working perfectly fine again.
