8. Troubleshooting
- No Display: Ensure the USB cable is securely connected to both the device and a working USB power source. Check if the vehicle's ignition is on.
- Inaccurate Speed Reading: Ensure the device has a clear view of the sky for optimal GPS signal reception. Speed accuracy may vary slightly based on GPS signal strength.
- Display Too Dim/Bright: The device features automatic brightness adjustment. Ensure the light sensor is not obstructed.
- No GPS Signal: The device requires an unobstructed view of the sky to acquire GPS signals. This may take a few minutes upon initial startup or in areas with poor satellite coverage (e.g., tunnels, dense urban areas).
