Product Description
Fit for all vehicles with standard OBD2 interface (1996 and later models). This M7 head up display combines OBD2 and GPS data to show real-time driving metrics on your windshield without requiring you to look down. After plugging into the vehicle’s OBD2 port, the unit reads engine water temperature, vehicle speed, engine RPM, and trip mileage directly from the ECU. The built-in GPS module provides speed and satellite time as a backup. An overspeed reminder lets you set a speed threshold; when crossed, the display beeps once. The device also tracks continuous driving hours and shows a symbol when it is time to take a break. If the engine control unit logs a fault, the display shows the code (e.g., P0300) on screen. You can clear codes using the device buttons. The projector includes a reflective film and adjustable mount. Brightness adapts manually. No external wiring or professional installation is required. This unit helps monitor engine conditions and driving habits continuously.
