What's wrong when the car navigation screen doesn't light up?

If the car navigation screen doesn't light up, it may be due to poor contact. If the screen only lights up when the car is started, it indicates that it requires a high instantaneous current to activate and then stays off. Car navigation systems utilize onboard GPS (Global Positioning System) in conjunction with electronic maps to conveniently and accurately guide drivers to their destinations via the shortest or fastest routes, making them excellent assistants for drivers. Another possibility is to check whether the navigation device's software is genuine or pirated. If it's pirated software, compatibility issues may arise, requiring the reinstallation of genuine software to resolve the problem.
As a driver with over a decade of experience, I've encountered the issue of a non-illuminating navigation screen several times. Usually, it's due to a blown mini fuse, especially when driving on bumpy roads. You can open the fuse box to check the fuse corresponding to the navigation system and try replacing it with a new one to resolve the issue. Additionally, low battery voltage can also cause the screen to malfunction, which is particularly common in older vehicles. If these checks don't reveal any problems, it might be due to loose or poor contact in the navigation system's power cable. I've personally disassembled the dashboard to tighten the screws, which fixed the issue. If you can't resolve it yourself, don't hesitate to take it to a professional repair shop, as driving without navigation can delay your route and compromise safety. Remember to check electronic devices during regular maintenance to avoid sudden failures.
