4. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| HUD does not power on. | No power supply; faulty USB cable; car's USB port is off. | Check USB cable connection. Try a different USB port or power source. Ensure the car is running or accessory power is on. |
| Inaccurate speed reading. | Poor GPS signal; initial calibration needed. | Ensure the vehicle is in an open area with clear sky view. Allow a few minutes for GPS signal acquisition. If persistent, check settings for speed calibration options. |
