I've handled quite a few cases of navigation display black screens, mostly due to power issues, such as blown fuses or loose battery connections causing power interruptions; display unit failures are also common, like screen aging or internal circuit damage, especially in humid or dusty environments where problems are more likely to occur; software errors are another major cause, with system crashes or failed updates leading to black screens; then there's the issue of wire wear or corrosion, where poor contact at connectors disrupts the signal chain; environmental factors like high temperatures can cause the display's overheating protection to fail. I recommend first checking the fuse box and connection lines, trying a simple system reboot, and if that doesn't work, heading to a professional repair shop promptly—after all, navigation failure affects driving safety. Regular vehicle maintenance to prevent issues beforehand can save a lot of hassle in the long run.
