Troubleshooting
HUD screen not powering up
Check that the charger cable is plugged in securely to the HUD and to the charger unit. Check
the HUD switch to ensure it is in the ON position. If there is still no display, please try the unit in
another car to test and analyse whether the car cigarette lighter is supplying power.
No speed, HUD powers off after 20 seconds or HUD will not automatically power on or off
When the starting voltage is less than 13.2V, the HUD will not power on. Please start the car
engine, then hold the button in for 5 seconds to enter into the settings menu, then navigate
through to settings menu 7. Push or pull the button to adjust the voltage from 132 to 128, at
which point the HUD should power on.
HUD will not automatically power off after the car is turned off
The HUD is designed for a default voltage value of 13.2v. When the voltage is above 13.2v, it will
automatically power on, then when it is lower than 13.2v is will automatically power off. If the
HUD does not power off automatically, hold the button in for 5 seconds to enter into the settings
menu, then navigate through to settings menu 7. Adjust the voltage level to 135 or higher.
Please note that the value shouldn't be set too high, as the HUD will not automatically power on
due to not receiving the set working voltage.
Inaccurate Speed
When the HUD is powered on, press and hold the button for 5 seconds to enter into settings.
The menu 0 will show the parameter of 107. Push or pull the button up or down to increase or
decrease the value according to the difference from your actual speed until it shows the correct
one. After making the adjustment, press and hold the button for 5 seconds to save.
Overspeed Alarm
The default value for the overspeed alarm is 120. Users can choose to increase/decrease this
value by themselves. When the HUD is powered on, press and hold the button for 5 seconds to
enter into the settings menu, then navigate to menu 1. The parameter will display 120, which
represents the speed at which the HUD will give an alarm once the car reaches that speed.
Push or pull the button up or down to set the desired speed, then press and hold the button in
for 5 seconds to save.
Cannot see the HUD clearly in sunlight
Check whether the HUD protective film is torn and that the reflection film is positioned correctly.
