1、Exquisite and unique design, independent of external light, stereo imaging is not ghostly. 2、No need for film, no extra reflection, plug and play, easy to operate, high-tech assisted driving is safer. 3、Powerful practical display, such as speed, water temperature, voltage, etc., HUD can eliminate the fault code displayed on the engine dashboard. 4、Early warning of car breakdown due to excessive water temperature and low voltage. OBD2+GPS dual mode for all models. 5、OBD mode shows fuel consumption, speed, single mileage, total mileage accumulation, travel time, driving direction, system time, intake pressure, etc. 6、After accelerated testing, braking test, reading data stream. 7、Overspeed, water temperature is too high, voltage is too low, faults can be alarmed. 8、Kilometers and miles, degrees Celsius and Fahrenheit can be switched freely. 9、Stereoscopic imaging uses a translucent semi-reflective lens to stereoscopically display information in the air.
