What Causes the In-Car Navigation Screen to Go Black?
3 Answers
Loose power voltage or cable faults, insufficient power supply can all cause the navigation device screen to go black. Additionally, severe battery depletion may also lead to the display automatically turning off and the screen going black. Below are the relevant explanations: 1. Dead Battery: If the battery is dead, the navigation device will not function, resulting in a black screen. If pressing the power button for a long time causes the screen to light up briefly before turning off again, it indicates the battery is dead and should be charged promptly. 2. Software Function Requires an Update: The need for a software function update can also cause a black screen. For example, if the navigation device's system is Android, some updated software may no longer be recognized by the original system, leading to a mismatch in functionality. In this case, you either need to upgrade the system or downgrade the software version.
I've been driving for over a decade and have encountered navigation screen blackouts several times, which is quite annoying. Possible causes include power issues, such as blown fuses or low battery voltage, leading to the navigation system losing power; loose or aged connection cables affecting signal transmission; hardware failures in the screen itself, like a broken backlight; software crashes or the need for updates, getting stuck on the loading screen; and sometimes external factors like overheating or impact damage. I think the first step is to try restarting the car's system and checking the fuse box to see if the navigation fuse has blown. It's also important to keep the system clean and avoid prolonged exposure to sunlight. If the problem persists, it's advisable to visit a repair shop as soon as possible for a check-up to avoid delaying your trip. Without navigation, long-distance travel can easily lead to wrong turns. Last time, I missed a gathering because of this, but thankfully my friend guided me over the phone in time.
I use my car daily to pick up and drop off my family, and a black screen on the navigation system affects safe driving. Common causes include the vehicle's device overheating and shutting down automatically; power interruption due to short circuits or fuse failures; screen hardware damage, possibly an LCD screen issue; software bugs causing the system to freeze or crash; or poor contact such as loose plugs. When dealing with it, first ensure the vehicle is parked in a safe location, then try removing the key and waiting a few minutes before restarting. Remember to have the wiring checked during regular maintenance and use reliable charging equipment to avoid abnormalities. If the screen goes black, don’t panic—use your phone’s navigation as an emergency backup. Last time this happened on a rainy day, my wife was worried our child would be late for school, but fortunately, I remembered the route and arrived on time. If there’s an issue with the car’s equipment, it’s best to have a professional technician inspect it.
