Why is the car navigation screen turning red?

[SanCora]

There are several reasons why a car navigation screen may flicker or turn red: 1. Check components: Verify whether the power socket has electricity and is securely connected; check if the car cigarette lighter is functioning properly; inspect whether the car charger plug equipped with the navigation device is reliably connected. Examine if there is an issue with the LCD screen. The possibility of a display screen problem cannot be ruled out. 2. Check the wiring: Loose screen wiring, wiring issues, or motherboard module problems may require board replacement. Frequent travel on bumpy roads can cause the screen wiring to become loose. It is advisable to have a repair technician disassemble and inspect it as soon as possible, as prolonged delay may lead to screen damage. Seek manufacturer repair or replacement.
