What are the reasons for the unresponsive car navigation screen?

[LeIsla]

The reasons for the unresponsive car navigation screen are: 1. The screen has reached the end of its lifespan; 2. There is an issue with the resistive touch screen; 3. The film applied on the screen has caused adhesive to stick to the screen surface; 4. The screen itself has malfunctioned, which could be due to touch screen damage, loose connections, wiring issues, etc. Solutions include using dishwashing liquid or essential balm to clean the adhesive residue on the screen. The built-in GPS antenna in the car navigation system receives data signals from at least 3 of the 24 GPS satellites orbiting the Earth. By combining this with the electronic map stored in the car navigation device, the system matches the position coordinates determined by the GPS satellite signals to pinpoint the car's exact location on the electronic map.
