I once experienced a sudden blackout of the car's display screen while driving, which gave me quite a scare. That day, the navigation suddenly disappeared on the highway, and I had to rely on memory to drive, which was extremely inconvenient. After checking at home, I found out it was a blown fuse—probably caused by too many external chargers drawing excessive current. The fuse was located in the box under the steering wheel, and replacing it fixed the issue. Another common cause is loose wiring; for example, my friend’s SUV had a loose connector behind the screen due to vibrations on bumpy roads, and simply reconnecting it solved the problem. If the screen remains black after restarting the engine, it might be due to screen aging or a software crash, requiring a professional diagnostic tool at a repair shop. Remember, a blacked-out display while driving can affect safety, so don’t hesitate to pull over and address the issue.
