What to Do When the Car Navigation Screen Goes Black?

[SanRichard]

The solutions for a black screen on car navigation are: 1. If the screen is completely black and does not turn on, first check if the car fuse has blown. If the fuse is blown, replace it, or use a multimeter to measure whether the B and ACC voltages are normal; 2. Promptly inspect whether there are any loose connections in the wiring. If found, simply reconnect the loose parts properly. The navigation device is a product of modern technology, mostly used in cars for positioning, navigation, and entertainment. With the increasing popularity of cars and road construction, intercity economic exchanges have become more frequent, making in-car GPS navigation devices particularly important. Navigation devices that combine accurate positioning, navigation, and entertainment functions can better meet the needs of car owners and have become a basic equipment in vehicles.
