How to Deal with a Black Screen on the Navigation System?
2 Answers
Solutions for a black screen on the navigation system: 1. Press and hold the navigation power button; 2. Check if the navigation software needs an update, as the original version may not support the new one, requiring contacting the manufacturer for a replacement; 3. Inspect the navigation connection port to ensure proper contact and reinsert the connector if necessary; 4. Use the reset button, located at the navigation exit, by gently pressing it with a toothpick or a paperclip. The built-in GPS antenna in the car navigation system receives data from at least three of the 24 GPS satellites orbiting the Earth. Combined with the electronic map stored in the car navigation device, it matches the position coordinates determined by the GPS satellite signals to pinpoint the car's exact location on the electronic map, which is commonly referred to as the positioning function.
Hey, last month my car navigation screen suddenly went black, which really freaked me out, but I gradually figured out some solutions. As an ordinary office worker, I rely on navigation for my daily commute. When the screen went black, I first pulled over to a safe area, removed the car key and waited for three minutes before restarting the vehicle to try a forced reboot—holding down the screen's power button for ten seconds sometimes works. If that doesn’t help, check the fuse box; the navigation fuse is usually labeled in a small rectangular box, often a blue one—replace it if it’s blown. If the screen still stays black, it might be a software crash. That time, I connected my phone to update the map app and managed to navigate temporarily. Don’t delay fixing it to avoid getting lost or causing an accident. Keep the system updated regularly and check it at least once a month.
