6. Nchọpụta nsogbu

If you encounter any issues with your VJOYCAR G20 HUD, please refer to the following common problems and their solutions:

• Ngwaọrụ anaghị agba ọkụ:
  • Ensure the USB cable is securely connected to both the HUD unit and the vehicle's USB port or car adapter.
  • Verify that the vehicle's ACC power is on. The device is designed to power on automatically with the vehicle.
  • If using a car adapter, ensure it is functioning correctly and providing 5V power.
• No GPS Signal / Display Shows "0" for Extended Period:
  • For first-time usage or after a long period of inactivity, it may take 10-30 seconds for the device to acquire a GPS signal.
  • Ensure the vehicle is outdoors with a clear view of the sky. The device cannot acquire a GPS signal indoors, in underground parking lots, or in tunnels.
  • Relocate the device on the dashboard to a position with less obstruction from the vehicle's roof or other components.
• Speed Reading Differs from Car Dashboard:
  • The GPS speedometer collects data directly from satellites, while car dashboards typically measure speed from tire rotation. A difference of 1%-5% is normal and expected. The GPS reading is generally considered more accurate.
• Display Brightness Issues (Day/Night):
  • The device is designed for clear visibility day and night. Ensure the display is not obstructed by direct sunlight or reflections. Adjusting the placement on the dashboard might help.
