RCD360 PRO3 Wireless Carplay Assistance & FAQs

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

Solutions:

• If your vehicle uses a large Quadlock connector, the standard power cable can be used directly.
• If your vehicle uses an ISO connector, an additional Plug-B for ISO cable is required: Product link.
• If your vehicle uses an MQB connector, this unit is not compatible. Please upgrade to RCD360 PRO3S.

Issue: The vehicle wiring has been modified or previously customized, which may cause incompatibility, especially related to CAN communication.

Solution: Please contact customer support and provide a clear photo of the original vehicle connector so we can identify the correct solution.

Issue: The head unit does not shut down completely after the ignition is turned off.

• The unit can still be powered on after removing the key.
• The button backlight remains illuminated.
• CarPlay remains connected while the vehicle is off.

Cause: This is not caused by the head unit itself. It is typically due to an outdated CAN Gateway version that does not transmit the shutdown signal correctly.

Diagnosis:

1. Headlight test: turn the headlights on and off. If the button backlight responds, CAN communication is partially working.
2. Bluetooth test: if Bluetooth works normally, some CAN signals are present but the shutdown signal may be missing.

Solution: Install the yellow power drain fix wire.

• If the wire was not included, please contact support and we will provide it free of charge.
• Follow the wiring instructions in the video below.
