GPS Display FAQ
1. There is no display on the screen, no power
Check whether the USB cable is damaged, replace the USB cable for testing, and prohibit using a voltage higher than 5V for power supply.

2. No speed,
The power-on satellite icon flashes to indicate the satellite search state. Move the car to an open road, and when the satellite icon stops flashing, it can be used normally.

3. Time calibration
After the satellite icon is flashing and the satellite is found, enter the sixth item of the setting item to adjust the calibration local time.

4. The speed is not allowed
Check whether the unit is correct, km KM/mile MPH, (speed unit switching reference setting item)
When the car leaves the factory, the manufacturer increases the speed displayed on the dashboard by 5-7%, and the international calibration is based on satellite data.
Fine-tune the vehicle speed, such as the meter displays 100km/h, the machine displays 105Km/h, and adjust the parameter value to 102.

5. The driving direction is displayed incorrectly
When there is no vehicle speed, the satellite cannot identify your driving direction, and it can be displayed normally only after the vehicle speed exceeds 5Km/h.

6. Turn off the buzzer
Turn the scroll wheel to the left for 2 seconds to turn off the buzzer, and turn the wheel left again for 2 seconds to turn on the buzzer.

7. Inappropriate time display
Due to the time error in various countries and regions, the time of our machine is the time of East 8th zone, so if the machine is different from your country’s time zone, please adjust it in the setting items.
