1 Answers
Car navigation system works by connecting the signals emitted from the navigator with satellites in space to detect the vehicle owner's specific location on Earth and then feed this information back to the navigator. The navigator then compares this data with the map stored in the memory card to display the exact location on the screen. The car navigation system is also known as the onboard GPS navigation system, primarily composed of the main unit, display screen, operation keyboard, and antenna. Functions of the car navigation system: 1. Navigation function; 2. Turn-by-turn voice prompt function; 3. Display of route and positioning; 4. Calculation of the specific speed of travel. The car navigation system features GPS global satellite positioning functionality, enabling the vehicle owner to know their exact location anytime while driving.
