Just a few days ago the screen of my car went black. I don't know what happened.
Can someone tell me what should I do please?

 

A common problem on some oyota models..

Search the internet on this problem as the fix appears trial and error or does not exist.

Try updating the software Toyota uses.

Could also be a loose connection to the screen but this requires getting into the unit.

The end result is many end up replacing the unit with aftermarket.
