A couple of days ago, my car's navigation screen suddenly went black. After fumbling around for a while, I realized it was due to a blown fuse. This is actually quite common – prolonged jostling can loosen wire harness connectors, leading to poor contact and power loss. High summer temperatures can also accelerate screen aging, resulting in blackouts. Another possibility is the infotainment system freezing, especially for owners using third-party cracked software, as the likelihood of software conflicts is much higher. Once when I encountered a black screen, it resolved itself after waiting half an hour for an automatic reboot. Lastly, damp wiring or water ingress into modules could be the culprit, with issues often arising after heavy rain. My advice is to turn off the engine and wait ten minutes before checking again. If that doesn’t work, inspect the fuse box location – it’s usually marked in the manual. Keeping the system updated regularly is crucial.
