My display screen went completely black. The blind spot warning system ds not work at all as well when the display screen went black. It’s completely unresponsive, no navigation, radio, entertainment anything. The a/c is on full blast as if it’s on defrost as well. And the language for the car went into German for some reason I have no idea why. It was working completely fine this morning when it happened and when I went to turn on the car it stopped working completely.
