Why did my car screen go black?
Restart Your Car’s Infotainment System
The reason you’re facing the black screen issue may not even be related to Android Auto on your phone. It could be that your car’s stereo system or head unit is malfunctioning, so you’re unable to use Android Auto. A quick fix for this issue is to restart your car’s head unit.

Why is my car radio display not working?
A damaged or defective fuse might lead your car radio display not to work. This particular fuse sits right between the display unit and the power line. If you installed a newer stereo system by replacing the stock one, there might be an issue where the aftermarket stereo won’t turn on due to a defective fuse.
