5. Troubleshooting
If you encounter any issues with your AMROOLOO G3, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply or faulty USB cable. | Ensure the USB cable is securely connected to both the device and a working power source. Try a different USB port or cable. |
| No data displayed or slow GPS signal acquisition. | Weak or obstructed satellite signal. | Ensure the device has a clear view of the sky. Move the vehicle to an open area away from tall buildings, tunnels, or dense foliage. Initial signal acquisition may take a few minutes. |
| Inaccurate speed reading. | GPS signal interference or calibration needed. | Ensure a strong GPS signal. If discrepancies persist, refer to the manual's settings section for potential speed calibration options (if available, not explicitly mentioned in provided data but common for such devices). |
| Display is too dim or too bright. | Automatic brightness adjustment or manual setting. | The device has a photosensitive hole for automatic brightness. Ensure it is not obstructed. If manual adjustment is desired, use the toggle key to navigate brightness settings (if available). |
Note on OBD vs. GPS Mode: This product operates solely on GPS mode, making it universally compatible. If you previously used an OBD-based display and encountered compatibility issues, this GPS-based system resolves those concerns.
