5.1. Weergavefuncties

The G1 HUD features a 2.6-inch HD display with the following indicators:

• Satellietpictogram: Flashes while searching for GPS signal. Stops flashing and remains steady once a satellite connection is established for normal use.
• Vehicle Speed Display: Shows current driving speed.
• Kompas: Displays driving direction (N for North, E for East, W for West, S for South).
• Snelheidseenheid: Indicates whether speed is displayed in KM/H (kilometers per hour) or MPH (miles per hour).

5.2. Wave Button Function

The G1 HUD is controlled via a single wave button. Its functions are:

6. Onderhoud

The G1 HUD requires minimal maintenance. Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials that could damage the screen or casing.

7. Probleemoplossing

If you encounter any issues with your G1 HUD, please refer to the following troubleshooting guide:

1. Screen without any display or no power:
   • Check if the USB cable is damaged. Try replacing it with another USB cable for testing.
   • Zorg ervoor dat de voeding voltage is niet hoger dan 5V.
2. No car speed displayed:
   • After HUD power-on, the satellite icon will flash as it searches for a satellite signal.
   • Drive the car to an open road. The HUD will start displaying speed once the satellite icon stops flashing and a stable GPS signal is acquired.
3. Onnauwkeurige snelheid:
   • First, verify that the speed unit (KM/H or MPH) is correctly set in the settings menu (refer to Section 5.4, Menu 5).
   • Car manufacturers often calibrate dashboard speed to be 5-7% higher than the actual speed (based on satellite data). If your dashboard shows 100 and the HUD shows 105, you can adjust the parameter value in the settings (refer to Section 5.4, Menu 1) to correct this discrepancy (e.g., set to 102).
4. Driving direction display error:
   • The driving direction will be displayed normally once the vehicle speed exceeds 5 KM/H.
5. Speed is still displayed after the car stops:
   • In areas with obstructions such as underground parking lots, tunnels, or underpasses, satellite signal may be unstable, leading to temporary speed display even when stationary. This is normal behavior due to GPS signal limitations.
6. To turn off/on the buzzer:
   • Long push the wave button to the left for 2 seconds to turn off the buzzer alarm. Repeat the action to turn it back on.

9. Gebruikerstips

• Eerste GPS-vergrendeling: When first powering on or after a long period of inactivity, the satellite icon may flash. Drive the vehicle to an open area to help the device acquire a stable GPS signal faster.
• Snelheidsnauwkeurigheid: If you notice a consistent difference between the HUD's speed and your car's dashboard speedometer, use the "Speed" adjustment setting (Menu 1) to calibrate it for better accuracy.
• Compass Functionality: The driving direction (compass) will only display accurately once your vehicle is moving above 5 KM/H.
• No Water Temperature Display: Please note that this device is a GPS speedometer and does not display engine parameters such as water temperature.
• Stroomverbruik: The G1 HUD is designed for zero power consumption when the car is turned off, as it uses a short power supply from the USB or cigarette lighter.
