GPS display FAQ

1. The screen without any display, and no power
   Check whether the USB cable is damaged, replace the USB cable for testing, and prohibit the use of voltage higher than 5V for power supply

2. Without car Speed
   After HUD power-on, the satellite icon flashes will start to find the satellite. Please driving the car to the road. It will work after it stops flashing

3. Inaccurate Speed

   • a. First check the speed unit is correct or not, the speed unit including KM/H and MPH, please refer to the setting to switch the unit.
   • b. The car manufacturers usually make the dashboard speed 5-7% higher than the ECU. The international standard is based on satellite data. (if the dashboard shows 100, and the device shows the 105, change the default value at 102)

4. Driving direction display error
   After the vehicle speed exceeds 5KM / H, the direction can be displayed normally.

5. Speed is still displayed after the car stops
   Under the underground parking lot, tunnel, under the overpass, there will be unstable satellite drift when there is obstruction.
