I had the same problem. eCall warning message. Rear cameras show a black screen, GPS stuck and also: the display lost its ability to automatically adjust to available light and switch night/day automatically.
I tried to reboot, as well as the Switch Off command in the menu. It did not help. So I reported the problem to Tesla via the app and made an appointment.
As I had to wait 2 weeks and fixing it also needed 2x 30-45 mins drive, I decided to try the disconnect 12v + Hi-Volt battery trick myself. This Youtube video proofed to be very helpful with that:
.
I am not a mechanical wizard, but this was an easy job taking me 5 minutes - because I kept on checking whether I was doing the right thing. And it immediately fixed all problems I encountered!
A few days later, having secured the fact that the car was still doing fine, I canceled the service appointment in the Tesla app. I was called within 30 minutes on what was happening. I explained and got confirmation that most likely, this should have solved all issues. If not, please report again to Tesla.
The Tesla guy also gave me one advice that I like to share here. If you reboot your car (foot on the brake pedal + pushing both steer wheel buttons), KEEP EVERYTHING PRESSED IN FOR 20 SECONDS. Apparently, the car will then take longer to restart which might already make the difference.
My last remark was to the Tesla guy. I told him to appreciate the call, but I would have strongly preferred to have a call shortly after I reported the problem, to instruct me on what I could already try myself before visiting the Tesla maintenance center. As this would have saved me (and in the future, other drivers) a lot of hassle, googling, experimenting and/or a preventable and time-consuming visit to a Tesla maintenance center.
