7. Troubleshooting

If you encounter issues after installation, consider the following troubleshooting steps:

• No Power to Android Unit: Double-check all power connections on the wiring harness. Ensure the vehicle's fuse for the radio is intact.
• Steering Wheel Controls Not Working: Verify that the CANbus box is correctly connected and configured in the Android head unit's factory settings. Ensure the correct CANbus brand and model are selected. Update MCU and configuration files if available.
• No Sound or Distorted Sound: Check audio connections from the harness to the Android unit and to the vehicle's speakers.
