Whats the M1 hudM1 is a GPS mode head-up display, unlike most head-up displays on the market, our designers made good use of the characteristics of the windshield to turn M1 into a new windshield HUD. Design conceptThe M1's screen design is very simple, the data projected onto the windshield cannot be too complicated, otherwise it will block the driver's view. So we designed it as a very simple speedometer, presenting only the most important data of speed in front of the driver's eyes, at a glance, simple and clear. Main functionsM1 displays speed, with speeding alarm and fatigue warning function, GPS compa shows direction. Speed is available in MPH and KM/H units, which can be adjusted in the setting. When there is over speed or continuous driving for too long, the product will emit a beeping sound to remind the driver, which is like a safety supervisor, always remind the driver to pay attention to driving safety, placing a mini M1 HUD inside the car will definitely add a lot of fun. Automated HUD 1The product is embedded with advanced light-sensitive elements, which can change according to the brightne. When the light is strong during the day, the product will automatically brighten, on the contrary, when the light is weak at night, the brightne of the product will also automatically become dark. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
