Troubleshooting
If you encounter any issues with your ACECAR G16, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Display / Unit Not Powering On | No power supply; Loose USB connection; Faulty USB cable/adapter. | Ensure the USB cable is securely connected to both the unit and the power source. Try a different USB port or car adapter. Check if the car's cigarette lighter socket is working. |
| Inaccurate Speed Reading | Weak GPS signal; Unit not properly calibrated (unlikely for GPS-based); Interference. | Ensure the unit has a clear view of the sky for optimal GPS signal reception. Drive for a few minutes to allow the GPS to stabilize. |
| Display Too Dim/Bright | Automatic light sensor issue; Extreme lighting conditions. | The unit has an automatic light sensor. Ensure the sensor (small aperture on the unit) is not obstructed. The brightness adjusts automatically. |
| Unit Does Not Turn Off with Car | Car's power outlet remains active after ignition off. | Some vehicle power outlets remain active. Disconnect the USB cable manually if this occurs, or use a power outlet that cuts off with ignition. |
