[Fully Disrupted - Perfect Clarity Head Up Display] Leave out the redundant features, our HUD display is solely designed for displaying driving speed, offering no double image even under intense noon sunlight. It is made easy to read, without needing to paste any film on your car glass unlike typical LED HUD displays in the market. [No more Destructive connections with GPS Speedometer] Our GPS-empowered speedometer procures speed data directly from GPS satellites, not requiring any connections to the car engine or OBD port. This allows for broader compatibility across vehicles - whether it's an SUV, ATV, Truck, Scooter, Golf Cart, Bus, Boat, Train, or Bike, the device can be optimally utilized. [Effortless Install and Easy-to-Use Design]No buttons, no settings, no manual intervention needed - just plug and play with the USB cable. If a USB port available in your car, connect the Cable; otherwise, use a car adapter. The device is engineered to be user-friendly and uncomplicated. [Automatic Power Management] Our HUD comes with built in vibration sensor. When your car is in motion, it switches on automatically and continues to display speed in large, clear fonts. After 3 minutes of no movement, the device will power off, ensuring no unnecessary power consumption. [Reliable] Please allow about 10-30 seconds for the device to get a GPS signal upon first use and note it cannot be used indoors.
