Troubleshooting
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 look for the satellite. Please driving
the car to the open road. It will work after it stops flashing
3.Time calibration
3.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 the 105, change the default value at
102)
5.Driving direction display error
Satellites cannot tell where you are driving when there is no speed. After the vehicle speed
exceeds 5KM / H, the direction can be displayed normally.
6.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.
7.Turn off the buzzer
Push left for 2 seconds to turn off the buzzer, do it again to turn on.
