What Causes the Car Navigation Screen to Display Distorted Images?
2 Answers
The reasons for a car navigation screen displaying distorted images include the car computer freezing, loose wiring harness clips, or failure of the car's infotainment module. Below are detailed explanations: 1. Car Computer Freezing: Modern vehicles are equipped with numerous electronic components, especially with the continuous updates and iterations of car connectivity systems. Many vehicles' multimedia systems have become increasingly complex, leading to a rise in issues with the car's display screen. You can try turning off the engine and restarting both the vehicle and the car computer to see if the display returns to normal. If repeated attempts fail to resolve the issue, schedule a visit to a 4S shop for inspection, updating, or repair of the relevant module. 2. Loose Wiring Harness Clips: Many wiring connections rely on clip-on plugs. When driving on bumpy roads or due to poor original installation quality, these clips may become loose or detached, causing the car's display screen to malfunction. In such cases, you will need to visit a 4S shop or repair facility to have the screen removed and the clips re-secured. 3. Infotainment Module Failure: This is a relatively common issue. Sometimes, due to the abundance of electronic components in the car, the display screen may show too much content, leading to interference between internal modules. This can easily cause problems with the infotainment system. Repeated restarts may not help, and the only solutions are to restore factory settings or visit a 4S shop for a system reflash.
Last time I was driving, the navigation screen went fuzzy, which really startled me, so I quickly pulled over to check. It could be that the display itself is damaged, such as the LCD screen aging or cracking after being bumped, or the wiring connections are unstable, especially the data cable from the main unit to the screen, which might loosen due to prolonged vibration. Another possibility is a bug in the navigation system software, where outdated updates cause compatibility issues. Power supply is also a factor—if the car's voltage is unstable, the display can malfunction. I suggest trying simple fixes first: restart the car or the navigation system, as sometimes a reboot can restore normal function. If that doesn’t work, consult a professional mechanic for a thorough check—don’t delay and risk bigger problems. Driving without navigation can easily lead to getting lost and compromise safety, especially during night driving, so it’s important to get it fixed promptly to avoid accidents.
