What to Do When the Navigation Screen Goes Black?
2 Answers
Here are the solutions for a black navigation screen: 1. Check the power supply. Press and hold the power button, and release it once the startup screen appears. If the screen turns off immediately, it indicates a low battery, and you should charge it right away. 2. Check the navigation software. Pirated software may cause compatibility issues, and reinstalling genuine software is necessary to resolve the problem. 3. Determine if it's caused by an upgrade. Original devices may not support newer software versions. In such cases, contact the manufacturer promptly to replace the navigation device. 4. Check for proper connections. Vehicle vibrations may loosen or disconnect wiring ports; simply reinsert them firmly. 5. Try pressing the reset button. There is a reset button near the disc slot of the navigation device; gently press it with a toothpick or paperclip.
Having driven for so many years, I've encountered the sudden blackout of the navigation screen a few times. Usually, I start with a basic check to avoid unnecessary expenses. If the screen goes black, don't panic; try turning the car off and then restarting it—sometimes the system just needs a reboot to come back to life. Next, check the screen brightness settings; if it's accidentally set to the lowest level, it might be mistaken for a black screen. Also, take a look at the fuses—find the one related to the navigation in the fuse box under the hood, and replace it if it's blown (remember to have a spare of the correct model). A black screen while driving is the most dangerous; I immediately pull over to a safe spot and switch to using my phone's navigation to avoid getting lost or causing an accident. For long-term prevention, regularly update the navigation system software to keep it running smoothly, which can prevent 90% of the issues.
