What Causes the Malfunction of Car Navigation Screen?
2 Answers
Car navigation screen malfunction is caused by computer crashes, and restarting the navigation system or restoring factory settings can solve the issue. Below are the reasons for navigation screen malfunction: Static electricity: Although the surface glass of the navigation touchscreen is treated to resist static electricity, it is still vulnerable to static, especially conductive media like oil stains and sweat from the driver's hands. High temperature: The navigation touchscreen is sensitive to high temperatures. If the car interior reaches around 40℃, it can cause the capacitive screen to drift, so it is advisable to avoid parking the car under direct sunlight. Magnetic fields: Magnetic fields inside the car, even a small magnet, can temporarily disable the touchscreen.
My navigation screen also acted up last week. After driving under the scorching sun for two hours that day, it suddenly became sluggish. Car screens are most vulnerable to high temperatures and direct sunlight, as heat can cause the integrated circuits inside the LCD panel to overheat and fail. Sometimes, excessive exposure can even disable the touch layer. Another common issue is applying low-quality tempered films. My friend’s SUV had this problem—the film was so thick that swiping fingers on the screen barely registered. System freezes are also frequent, especially when the map loads large files and suddenly crashes. Try forcing a reboot first by holding the volume button for 10 seconds. If that doesn’t work, consider wiring issues—I remember my old car three years ago had a loose connector, and a quick fix at the repair shop did the trick. Always try to park in the shade to avoid direct sunlight on the screen.
