5. Operating Features

This wiring harness is designed to integrate seamlessly with your aftermarket Android head unit, allowing it to utilize several original vehicle features.

5.1. JBL Amplifier Support

The harness includes a Canbus decoder that enables communication with the vehicle's original JBL amplifier system. This ensures that the aftermarket head unit can properly power and control the existing premium audio system.

5.2. Steering Wheel Control Retention

The integrated Canbus system also allows for the retention of your vehicle's original steering wheel controls. After installation, you may need to configure the steering wheel controls within your aftermarket head unit's settings menu to map the buttons correctly.

  • Verify the vehicle's fuse for the radio is intact.
  • Ensure the aftermarket radio itself is functional.
• No Sound or Poor Sound Quality:
  • Confirm all speaker wires (FL+, FL-, FR+, FR-, RL+, RL-, RR+, RR-) are correctly connected to the aftermarket radio.
  • Ensure the JBL amplifier is receiving power and is properly integrated via the Canbus decoder.
  • Check the audio settings on your aftermarket head unit.
• Steering Wheel Controls Not Working:
  • Verify that the KEY-1 and KEY-2 wires (if applicable to your radio) are correctly connected.
  • Access the steering wheel control learning function in your aftermarket head unit's settings and follow the on-screen instructions to program the buttons.
  • Ensure the Canbus decoder is properly connected and functioning.
• Reverse Camera Not Activating:
  • Check the connection of the BACK (Reverse Signal) wire to the aftermarket radio's reverse input.
  • Ensure the reverse camera itself is powered and properly connected to the head unit's video input.
