What to Do When the Navigation Screen Goes Black?
2 Answers
Navigation screen blackout solutions: 1. Check the battery level and charge promptly: If the battery is dead, the navigation device won't function, resulting in a black screen. Method to check: Press and hold the power button. If the screen lights up briefly and then turns off, it indicates the battery is depleted and needs charging. 2. Compatibility error, revert to official software: Some car owners use pirated software for their navigation devices, which often leads to compatibility issues, manifesting as crashes, freezes, and in severe cases, black screens. Owners should reinstall the official software. 3. Poor connection, secure the navigation device's port plug: Sometimes, due to vehicle vibrations or initially loose connections, the plug may become loose over time. 4. Software upgrade: For example, if the navigation system is Android-based, some updated software may not be recognized by the original system, causing functional mismatches. In this case, consider upgrading the system. 5. Factory reset: Most navigation devices have a reset button to prevent issues like freezing. Use a small, slender object like a toothpick to press the reset button. 6. Repair the circuit board: If the display is damaged due to a burnt circuit board, it may emit a strange odor or show color changes. However, these symptoms might not always be present. In such cases, seek professional repair services.
Honestly, I've experienced sudden navigation screen blackouts myself, and it's incredibly frustrating. At first, I thought it might be a dead battery or system crash, but I later learned a trick: try restarting the navigation system first. Many cars have a dedicated reset button, or you can find a restart option in the settings. If the screen remains black, it could be a blown fuse—check the fuse box and replace the relevant fuse. Don't forget to inspect the wiring connections for looseness; sometimes bumpy roads can cause plugs to come loose. If neither restarting nor replacing the fuse works, the hardware might be damaged—don't push your luck and head to a professional repair shop immediately to avoid ruining your trip. Oh, and never fiddle with it while driving—safety first! It's also a good idea to regularly check for system software updates to prevent freezes.
