What Causes the Touchscreen Failure in Car Navigation Systems?

[OSebastian]

Car navigation screen touch failure can be caused by: 1. Screen lifespan expiration; 2. Issues with the resistive touchscreen; 3. Adhesive from the screen protector sticking to the screen surface; 4. Screen damage; 5. Loose connections. The working principle of a car navigation system involves signals sent by the navigator connecting with satellites in space to detect the vehicle's exact location on Earth, which is then fed back to the navigator. The navigator compares this data with the maps stored in the memory card to display the precise location on the screen. Functions of a car navigation system include: 1. Navigation; 2. Turn-by-turn voice prompts; 3. Displaying routes and positioning; 4. Calculating the exact driving speed. Car navigation systems feature GPS (Global Positioning System) functionality, allowing drivers to know their exact location at any time while driving.
