Troubleshooting

1. The screen is 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 look for the satellite. Please drive the car to the open road. It will work after it stops flashing

3. Time calibration
   When the satellite icon flashes and no satellite is received, enter item 6 of the setting item to adjust the local time zone. The default is East Zone 8.
   After the satellite icon flashes and the satellite is found, enter item 6 of the setting item to adjust and calibrate the local time.

4. 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 mode 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 105, change the default value to 102)

5. Driving direction display error
   Satellites cannot tell where you are driving when there is no speed. After the vehicle speed exceeds 5 km / H, the direction can be displayed normally.

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

7. Turn off the buzzer
   Push left for 2 seconds to turn off the buzzer, and do it again to turn it on.
