Smart HeadUp Display: A smart headup display that helps you read a variety of vehicle driving data without lowering your head, with data projected on the windshield. Rich Display Content: The HUD displays a rich set of information, including speed, driving mileage measurement, engine speed, water temperature, battery voltage, instantaneous fuel consumption, average fuel consumption, mileage measurement, shift reminding, fatigue driving reminding, low voltage alarm, temperature alarm, speed alarm, engine fault alarm, fault code elimination, and switching between kilometer and mile. HD Display: Data are displayed on a 5.5 inch large screen in definition, then projected onto the windshield. The multicolor design makes the display easier to read, and nanotechnology eliminates unwanted reflections to make display information sharper. Outstanding Performance: Auto power on and off with vehicle started and shutdown, efficient on the car battery, while retaining the manual switch mode for control of the HUD. Automatic and manual brightness adjustment mode provides a glare driving experience. Use scenarios: On long highway trips, monitor speed, fuel consumption, engine temperature, and mileage without taking your eyes off the road. During urban commuting, rely on shift reminders, fatigue driving reminders, and alarms while switching between kilometer and mile. In night driving, enjoy glare readability thanks to auto/manual brightness control and antireflection display.
