Yesterday I was driving and attempted to control my air flow speed/AC control which ordinarily shows up on the MMI screen right??? well nope out of the blue nothing was displaying on the screen. It just decided not to work.

I turned the car on and off a few times, rebooted the MMI and it came back on it's own.

Just a head up. Also, if someone has had this issue let me know if there is a way to fix it.

Thanks and
CHEERS.
