Head-up display: The HUD display shows only the driving speed. No projection film on the car windscreen is required. Even in strong sunlight, no double images are produced, so the speed remains clear and easy to read. Clear GPS speed measurement: The speed is accurately recorded via GPS satellites, independently of the vehicle engine. No connection to the vehicle's circuit board or OBD port is required, which increases the safety and versatility of the device. Versatile compatibility: The device is suitable for almost all vehicle types, including SUVs, ATVs, pick-up trucks, scooters, golf carts, buses, boats, bicycles and motorcycles. It is a universal solution for different means of transport. Easy installation: Setup is straightforward. No buttons, settings or operating instructions are required. Plug-and-play via USB cable: Connect directly to the vehicle's USB port or use a car adapter if no USB port is available. Automatic on/off: A built-in vibration sensor activates the device as soon as the vehicle moves. If the vehicle is stationary for more than three minutes, it switches off automatically to save energy. In standby mode, it consumes no power and is therefore particularly efficient.
