6. Troubleshooting
If you encounter any issues with your AMROOLOO Head-up Display, please refer to the common problems and solutions below. If the problem persists, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Display not turning on / No data | Incorrect mode selected, loose cable, car not compatible with OBD mode. | Ensure cables are securely connected. If using OBD mode, try switching to GPS mode. Verify your car's OBD compatibility (cars after 2009 generally support it). |
| Inaccurate speed reading | Calibration needed, GPS signal interference. | The device may require manual calibration for speed accuracy. Refer to the full instruction manual for calibration steps. Ensure clear line of sight for GPS signal. |
| Display shuts down randomly | Power supply issue, device overheating. | Check power cable connection. Ensure the device is not exposed to excessive heat or direct sunlight for prolonged periods. |
| Screen reflection issues (e.g., not reflective in sun) | Direct strong sunlight, device overheating. | This can occur in very strong direct sunlight. The reflection should return to normal once the device cools down or is out of direct harsh sunlight. |
