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 turning on the HUD, the satellite icon will flash while it
   starts searching for satellites. Please drive the car on the road
   until the flashing stops to ensure proper functionality.

3. Inaccurate Speed:

   a. Check if the speed unit is correct (KM/H or MPH), and adjust
   it accordingly in the settings.
   b. Car manufacturers usually make the dashboard speed 5-7% higher
   than the ECU. The device follows the international standard based
   on satellite data. If there is a discrepancy between the dashboard
   and HUD speed, adjust the parameter value to match the actual
   speed.

4. Driving Direction Display Error:

   The direction display will work normally when the vehicle speed
   exceeds 5KM/H.

5. Speed is still displayed after the car stops:

   In underground parking lots, tunnels, or under overpasses, there
   may be unstable satellite drift due to obstructions.

6. Turn off the buzzer:

   Push left for 2 seconds to turn off the buzzer. Repeat the
   action to turn it on again.
