My 2014 MCU1 just got stuck this morning on the rear camera view - it's displaying the rear camera view while the car is on or off, and I'm able to drive in some kind of limited functionality mode with no access to my own settings. I've tried both the double-scroll and the four-finger reboot method - neither is managing to reboot the MCU touchscreen.
Has anyone had an experience where the center screen was eventually able to reboot, after getting stuck on the rear camera view? I'm just trying to survive for a few weeks until I can get this fixed. My SC appointment is a couple of weeks away. The main function I would like to recover, even if just temporarily, is to be able to adjust my max charge level.
Thanks for any advice folks may be able to offer.
