Why is the car navigation screen turning red?
4 Answers
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.
Encountering a red-tinted navigation screen issue, I've personally experienced it several times, with several possible main causes. The most common is accidental display setting misadjustment, such as altered RGB color balance or errors in system preset modes. Accidentally touching an option while operating the navigation menu can result in excessive red tones. Another possibility is hardware aging; car navigation screens, when used for a long time, can develop color shifts like old televisions, especially if exposed to high temperatures for extended periods, leading to internal LCD degradation and color changes. On the software side, failed system updates or bugs can disrupt display settings, and restarting the vehicle or resetting the system may temporarily resolve the issue. If there are dead pixels or flickering on the screen, it suggests loose connections or motherboard failure, requiring professional inspection. To avoid distraction while driving, it's recommended to immediately check the settings menu to adjust color values. If that doesn't work, promptly visit a repair shop for assistance, and minimize direct sunlight exposure to prolong screen lifespan.
Having driven for many years myself, I find that reddish navigation screens are not uncommon, mostly due to settings or hardware issues. You can try fixing it yourself: First, enter the system settings to check color options and try reducing the red gain value to restore normal display. If that doesn’t work, attempt a soft reboot of the navigation system by disconnecting the car battery for a few minutes and then reconnecting to reset it. Loose screen cables can also cause signal transmission errors—gently press the edges of the screen to see if there’s any change in response. Another common cause is outdated software or update conflicts; upgrading to the latest version can fix many display glitches. Environmental factors like high temperatures can also accelerate screen aging, leading to a reddish tint. If you can’t resolve it, avoid forcing a fix to prevent damaging other components. Regular maintenance of navigation software and checking connections can prevent minor issues from turning into major headaches.
In my driving experience, the red tint on the navigation screen could be due to issues with the screen itself, such as aging discoloration or unstable connections. Car screens are prone to color shifts after several years of use, similar to aging devices. Incorrect system settings or software bugs may also disrupt color display. It's recommended to first try a simple restart of the navigation system to see if it recovers. If that doesn't work, check the settings menu to adjust the color balance. High temperatures and direct sunlight can worsen the problem, so try to avoid direct exposure when parking. When navigation abnormalities affect direction judgment, use a smartphone as a backup to ensure safety. The key is not to delay driving.
