Issue: The power cable does not match the original vehicle connector.

Solutions:

• If your original car plug is a large Quadlock plug, you can directly use our standard power cable.
• If your car uses an ISO plug, you’ll need the special Plug-B for ISO: Product link.
• If your car has an MQB plug, this unit is not compatible. Please switch to RCD360 PRO2 or RCD360 PRO3S.

Issue: The original car wiring has been modified or previously customized, causing incompatibility (especially CAN signal mismatch).

Solution: Please contact customer service and send a clear photo of your original car plug so we can identify the correct solution.

Issue: The stereo does not completely shut down after turning off the ignition. Common symptoms include:

• The stereo can still be powered on after removing the car key.
• The button backlight stays illuminated.
• CarPlay remains connected even when the vehicle is off.

Cause: This is not caused by the head unit itself. It is often due to an outdated CAN Gateway that fails to transmit the shutdown signal correctly via CAN communication.

Diagnosis checklist:

1. Headlight sync test: turn headlights on/off — does button backlight respond? → If yes, CAN is partially working.
2. Bluetooth test: if Bluetooth works normally, some signals are working but shutdown communication may be missing.

Solution: Use the yellow power drain fix wire:

• If it was not included, please contact us — we’ll send it free of charge.
• Follow the wiring instruction video below.
