My CID seems to shutdown or reboot about once or twice a day now when car is parked (i.e. when I enter the car, the main touchscreen is on and working fine, but the CID is either black or in the process of rebooting). One time the screen turned completely white and required several forced reboots to clear up. Didn't happen with prior firmware. Late 2014 Model S with AP1 and MCU1. Anyone experience similar? It has been hot here so could be heat related too.
