Wiring Diagram

- Power Connection: Connect the yellow wire directly to the car battery (constant 12V). Connect the black wire to ground. The red wire should be connected to an ignition-switched power source (ACC) to ensure the radio turns off with the vehicle. Do not connect the red and yellow wires together to a constant power source, as this will prevent the radio from turning off and may drain your car battery.
- Speaker Connections: Connect the speaker wires according to the diagram, ensuring correct polarity for each speaker.
- Rear Camera: Connect the rear camera video input and power as shown.
- DAB Antenna: Connect the DAB antenna to the designated port.
- External Microphone: Plug the external microphone into its dedicated input for improved call quality.
DAB Antenna Installation
For optimal DAB+ signal reception, install the DAB antenna correctly. It is recommended to leave a 2-3 cm gap from the window frame. Before installation, remove the protective film from the DAB antenna. The copper part must be connected to metal (ground electrode).
