7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power from cigarette lighter; loose connection; faulty power cable. | Check cigarette lighter connection. Ensure the car charger is securely plugged in. Test the cigarette lighter with another device. Try a different power cable if available. |
| Wireless Carplay/Android Auto not connecting. | Bluetooth/Wi-Fi off on phone; incorrect pairing; interference. | Ensure Bluetooth and Wi-Fi are active on your phone. Forget the device in your phone's Bluetooth settings and re-pair. Move phone closer to the unit. Ensure no other devices are interfering with the connection. |
| Poor audio quality via FM transmitter. | Interference from other radio stations; car charger too close to dashboard. | Find a clear, unused FM frequency. Adjust the position of the car charger to minimize interference. Consider using AUX or Bluetooth output for better quality. |
| Dash cam records in short intervals (e.g., 60 seconds). | This is normal loop recording behavior. | This is the intended function of loop recording. The device records in segments to manage file size and overwrite older footage. Important events are typically locked and not overwritten. |
| Screen randomly turns off/reboots. | Unstable power supply; overheating; software glitch. | Ensure stable power connection. Check if the unit is overheating (e.g., direct sunlight). Try resetting the device (if a reset button is available, refer to Figure 2.1 for location on back of unit). If persistent, contact customer support. |
