What is generally broken when the navigation screen goes blank?

[OMary]

The causes of a blank screen in a car navigation system include unstable current, screen damage, wiring issues, IC and motherboard problems, as well as full memory or insufficient memory leading to navigation program errors causing the blank screen. Solutions: When the car navigation screen goes blank, the first step is to try restarting by cutting off the power. If that doesn't work, you can delete some unimportant content. Finally, you can also take it to a 4S store to upgrade the navigation board. Car navigation uses onboard GPS (Global Positioning System) in conjunction with electronic maps to conveniently and accurately guide drivers to their destination via the shortest or fastest route, making it a great assistant for drivers.
