1. The vehicle head-up display displays a variety of data in real time, including vehicle speed, clock, speed, voltage, water temperature, driving time, driving distance, number of satellites, altitude, azimuth, longitude and latitude, oil temperature, acceleration test, brake test, turbine pressure, engine load, etc. 2. Built-in 6 alarm functions, overspeed alarm/high water temperature alarm/low pressure alarm/high pressure alarm/fatigue driving reminder/vehicle fault reminder. When a fault occurs, the main interface will display a blue information reminder and a beep will sound. 3. The interface design allows switching between multiple interfaces, with larger fonts and clearer and smoother pictures. Equipped with a photosensitive system, the screen brightness is automatically adjusted according to the current environment. 4. Built-in multi-positioning system, which can receive up to 32 satellites, can display high-precision altitude, time, longitude and latitude, location and other information, which is very suitable for outdoor or self-driving needs.
