3.2 Pre-Installation Steps

1. Disconnect Battery: Before starting any electrical work, disconnect the negative terminal of your vehicle's battery to prevent electrical shorts.
2. Remove Factory Radio: Carefully remove the trim panels and screws securing your existing car radio. Refer to your vehicle's service manual for specific instructions.

3.3 Wiring Connections

Connect the provided wiring harness to the corresponding ports on the Leadfan stereo unit and your vehicle's factory wiring. Ensure all connections are secure.

• Power Cable: Connect the main power harness.
• RCA Cable: For external audio/video connections.
• USB Cables: Connect for USB devices and wired CarPlay/Android Auto.
• Reverse Input Cable: Connect for backup camera functionality.
• GPS Antenna: Mount the GPS antenna in a location with a clear view of the sky (e.g., dashboard, under the windshield) for optimal signal reception.
• Radio Antenna: Connect the vehicle's radio antenna.
• External Microphone: Plug the external microphone into its dedicated jack on the RCA cable for improved call quality.

3.3.1 Testing the Unit (Bench Test)

To test the unit before full installation, combine the red and yellow wires of the power supply and connect them to the positive side of a 12V power source. Connect the black wire to the negative side of the power supply. Ensure the voltage is exactly 12V; exceeding this may damage the radio.

3.4 Backup Camera Installation

The included backup camera requires running a wire from the rear of the vehicle to the stereo unit. The 12V barrel connector and RCA plug on the camera wire are not detachable, which may necessitate drilling a sufficiently large hole for cable routing. Connect the camera's video output to the 'Reverse Input' on the stereo unit and its power to the vehicle's reverse light circuit.
