3.3 Canbus Connection
If your car has original features like steering wheel buttons, door information display, large screen display, or reversing tracking, a Canbus module is required. Otherwise, it is not needed.
- If using a Canbus: Connect the Canbus module. DO NOT connect the small black plug. Select power cable according to the original vehicle interface. Disconnect the small black plug. Connect Canbus to the white connector. Choose the correct protocol for your car model in 'Car Settings' -> 'Factory (password 000000)' -> 'CarType settings' -> 'Xinpu' -> 'VW PQ'.
- If not using a Canbus: Connect the power cable to the original vehicle interface. DO NOT connect the small white plug. Connect the small black plug.

The right diagram shows wiring for a car not requiring Canbus, indicating to connect the small black plug and not the small white plug.
3.4 Connector Confirmation
The unit typically includes 36-pin and 40-pin ISO power harnesses. If your car's connector matches the 50-pin type shown in the image, you will need to purchase an additional adapter.

3.5 Reversing Camera Installation
The reversing input must be connected even if a reversing camera is not used. For camera wiring:
- Connect the positive pole of the power supply of the car's reversing light.
- Connect to the negative pole of the car's reversing light.
- The reversing trigger is controlled by the stereo, so no separate connection is required for the trigger.
Note: The white plug must be connected to the main device for Bluetooth and WiFi signals to function correctly.

6. Troubleshooting
If you encounter issues with your CAMECHO A4151, refer to the following common troubleshooting steps:
6.1 No Sound Output
If the car media player is experiencing power consumption issues or no sound, try the following solutions:
- Confirm that the Canbus and A&B ports of the power line are connected at the same time. Do not connect them simultaneously.
- If the Canbus is connected, try unplugging it to see if the issue persists. This can help determine if the problem is Canbus-related.
- After turning off the engine, confirm whether the ACC red wire of the power supply still has electricity. If it does, it indicates a wiring error. Reconnect the ACC red wire separately.
- If your Canbus is not from Simple Soft, consider replacing it with a Simple Soft Canbus.
- If using an external amplifier, ensure the AMP cable from the RCA output is connected to the AMP cable of the power harness. Also, connect the AMP cable to the ACC cable of the power harness. For power amplifiers, connect the power cable of the amplifier to the ACC cable of the power harness.

- Ensure Bluetooth is enabled on both your phone and the car stereo.
- Delete previous pairings on both devices and attempt to pair again.
- Restart both the car stereo and your phone.
- Ensure the white plug for Bluetooth/WiFi signals is securely connected to the main device.
6.3 General System Unresponsiveness
If the unit becomes unresponsive:
- Perform a soft reset by pressing the reset button (if available) or by turning off the vehicle ignition and restarting.
