- Ensure your car's dashboard opening is compatible with the standard double din size (approximately 7 inches wide by 3.8 inches high).
- Disconnect the car battery's negative terminal before starting any wiring.
- Familiarize yourself with the wiring harness provided.
4.2 Wiring Connections
Refer to the wiring diagram provided in the 'What's in the Box' section and the specific rear view wiring diagram below for detailed connections.
- Power Cable: Connect the power cable to your car's power supply according to the diagram.
- RCA Cables: Connect audio and video input/output cables as needed for external devices (e.g., amplifiers, headrest monitors).
- USB Cables: Connect the dual USB interfaces for media playback, charging, or wired Android Auto.
- GPS Antenna: Mount the GPS antenna in a location with a clear view of the sky for optimal signal reception.
- Rear Camera Input Cable: This cable is essential for the backup camera functionality.
4.3 Backup Camera Wiring
The included AHD backup camera requires specific wiring for proper operation:
- Camera Power: The red wire of the backup camera connects to the positive (+) back battery supply (e.g., reverse light power). The black wire connects to the negative (-) battery supply (ground).
- Video Input: The yellow RCA video output from the backup camera connects to the "CAM IN" port on the rear of the car radio.
- Trigger Wire: Locate the wire labeled "BACK" or "REVERSE" on the car radio's wire harness. This wire needs to be connected to the positive power supply of your car's reversing light. This signal tells the head unit to automatically switch to the reversing image when reverse gear is engaged.
