8. Troubleshooting
If you encounter issues with your Eonon Q50Pro, refer to the following common problems and solutions:
- Unit Does Not Power On:
- Check all power connections and fuses.
- Ensure the vehicle's ignition is on.
- Battery Drain Issue:
- Some users have reported battery drain if the unit remains active after the car is off. Navigate to Settings and ensure the CarPlay/Android Auto sleep setting is configured to "no sleep" or to power off with the ignition. This ensures the unit fully shuts down when the car is off.

- Ensure a stable USB connection (if wired) or Wi-Fi connection (if wireless).
- Restart your smartphone and the car stereo.
- Check for software updates for both the stereo and your phone's operating system.

- Bluetooth Audio Issues:
- Ensure your phone is properly paired and selected as the audio output device.
- Try unpairing and re-pairing the device.
- Verify that the volume on both the stereo and your phone is turned up.
- Apps Crashing/Freezing:
- Close and reopen the application.
- Clear the app's cache in Settings > Apps & notifications > [App Name] > Storage & cache.
- Ensure sufficient free storage space on the unit.
- Steering Wheel Controls Not Working:
- Verify that the CAN Bus decoder is correctly connected.
