Regarding the issue of the GL8 center control screen going black, I've encountered various possibilities in my car repair experience. The most common cause is software freezing. Try holding down the power button for more than 10 seconds to reboot the system, just like restarting a phone. It could also be a blown fuse - open the fuse box and try replacing the one corresponding to the screen. Loose wiring connections can also cause this problem, so check for loose or corroded plugs. Hardware damage like screen failure is more complicated and requires professional diagnostic tools at a 4S shop. To prevent issues, avoid frequently turning the screen on/off during normal use to reduce strain. When the screen goes black and navigation fails, remember to pull over safely and avoid driving blindly. If simple checks don't resolve the issue, promptly seek professional help from a technician without delay.
My GL8 also experienced a sudden black screen while driving when I needed navigation the most, which was quite frustrating. I first tried restarting the system by holding the power button until it rebooted, which sometimes worked. If that didn't help, I checked if the fuses were intact and replaced them myself a few times. Additionally, software conflicts are common, especially after updates, so try rolling back or updating the firmware. If the issue is due to aging wiring or dirty connectors, a simple cleaning might fix it. If the screen goes black while driving, I recommend pulling over immediately and switching to mobile navigation for safety. To prevent this, avoid running too many apps simultaneously during daily use to reduce system load.
