  • Red Wire (ACC+) and Yellow Wire (BATT+): Connect to a 12V positive (+) power source.
  • Black Wire (GND): Connect to a negative (-) ground.
  The unit should power on.

3.2 Wiring Connections

Refer to the included manual for the complete wiring harness diagram. Key connections include:

• Power:
  • Yellow Wire (BATT+): Connect to constant 12V+ (for memory preservation of settings and radio presets).
  • Red Wire (ACC+): Connect to switched 12V+ (ignition/accessory power).
  • Black Wire (GND): Connect to vehicle chassis ground.
• Speakers: Correctly connect the eight speaker wires (four channels: Front Left/Right, Rear Left/Right) to the corresponding vehicle speaker wires, observing polarity (+ to +, - to -). Incorrect connection can result in no sound or poor audio quality.
• Backup Camera: Connect the video RCA plug from the included camera to the "CAM IN" port on the stereo. Connect the camera's red power wire to the vehicle's reverse light circuit.
• Steering Wheel Control: Connect the included wireless steering wheel control adapter as per its instructions to interface with your vehicle's controls.
