2.4 Steering Wheel Control (SWC)
The unit supports most factory multi-function steering wheel buttons. The setup process depends on whether your vehicle has a CANBUS decoder.
- Without CANBUS Decoder: Connect the steering wheel control wires (Key1/Key2) in the power cable to the corresponding port or wire of your original car. Then, go to the 'Steering Wheel Key' manual match settings in the unit's interface to activate button functions.
- With CANBUS Decoder: Connect the CANBUS before powering on the machine. Then, navigate to 'Apps' > 'Settings' > 'Factory Settings' (password: 8888 or 8317) > 'Vehicle' > 'Automotive type' to select the matching brand and model year for proper SWC functionality.

5. Troubleshooting
If you encounter issues with your Roinvou Android Radio, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Unit does not power on. | Check power cable connections. Ensure the vehicle's ignition is on. Verify the ACC wire is properly connected. |
| No sound or poor audio quality. | Check speaker wiring. Ensure volume is not muted. Adjust EQ settings. If using a factory amplifier, ensure proper wiring or consider a line output converter if experiencing ground loop noise. |
| Bluetooth connection issues. | Ensure Bluetooth is enabled on both the unit and your phone. Try unpairing and re-pairing the device. Ensure the phone is within close proximity to the unit. |
| GPS signal is weak or inaccurate. | Ensure the GPS antenna is properly connected and placed in an area with a clear view of the sky (e.g., on the dashboard). |
| Backup camera not displaying. | Check camera power and video connections. Ensure the reverse input trigger wire is correctly connected to the reverse light circuit. |
| Steering Wheel Controls not working. | Verify SWC wiring. Perform the SWC learning process in the unit's settings (refer to Section 2.4). Ensure correct CANBUS decoder settings if applicable. |
| Navigation voice too low with music. | Adjust navigation voice volume settings within the navigation application or the unit's sound settings. Some apps may have independent volume controls. |
| Unit becomes unresponsive or freezes. | Perform a soft reset using the reset button (if available) or by turning off the vehicle's ignition and restarting. If issues persist, a factory reset may be necessary (note: this will erase all user data). |
