When I turn on the car in the summer or even in winter if the car is in the garage in the heat the touchscreen turns on immediately. Now, in winter if I leave the car outdoors with the cold, in the morning when I turn on the car, the screen remains black for about 10/15 minutes then turn on and all the commands work. During this period they do not work the temperature controls, AC, fan and navigator, only the radio works. I did not make any upgrade of the software and it is clear that it is a problem due to the temperature, now I would like to know if in addition to the fuse in the passenger compartment (which works) there is also a relay somewhere that starts the LCD touchscreen
