My Gv80 is almost a year old. I've had random, intermittent times where the controller dial (the large dial above the shifter dial) doesn't work for changing the XM station. It might happen when I head out , then later when I've stopped for a bit and restarted the car, it's fine. When it doesn't work for changing stations, it still works for changing things on other screens. I took it to the dealer, who of course couldn't re-create the problem. Then a few days after I took it home, It recurred and I took a video , so I could send it to them to show the problem(which I should have done before I went to the dealer). Luckily there are redundant ways to change the station, but this is annoying (along with a variety of other tech glitches that I won't get into here)

Has anyone else had this issue? And more importantly , any resolution?
