3. Installation

3.1. Before Installation

Before proceeding with the full installation in your vehicle, it is highly recommended to test the unit. Due to potential impacts during transit, testing the device beforehand can prevent issues. Connect the unit to a 12V power supply (yellow and red wires twisted together to positive, black to negative) and verify basic functionality.

3.2. Main Wiring Diagram

Refer to the following diagram for proper wiring connections. Incorrect wiring can lead to malfunction or damage.

Main Wiring Diagram: Shows connections for power, speakers, steering wheel controls, and other interfaces.

• Power (12V): Connect the Yellow (B+) and Red (ACC) wires to a 12V positive power source. The Yellow wire maintains power for memory function. The Black (GND) wire connects to ground.
• Speaker Wires: There are 8 speaker cables. Each cable must not be grounded, shared, or touch other lines. Improper speaker wiring can result in no sound, distorted sound, or overheating.
• Steering Wheel Control (KEY1, KEY2): Connect to your vehicle's steering wheel control wires.
• ILLUMINATION: Connects to the vehicle's backlight circuit for illumination synchronization.

3.3. Reversing Camera Installation

Follow these steps to install a reversing camera. Ensure all connections are secure.

Reversing Camera Installation Diagram: Shows connections for video input and reverse light trigger.

1. Find Wiring Ports: Locate the reverse control line (pink wire) on the unit's power line and the CAM video input interface on the rear.
2. Connect Reverse Control Line: Connect the pink reverse control line to a 12V positive source. This will trigger the screen to turn blue when reversing.
3. Camera Connections: The camera typically has two plugs. Connect the red plug to the power cable and the yellow plug to the video cable.
4. Powering the Camera: Connect the red wire of the camera's power cable and the video cable's red wire to the positive pole of the reverse lamp. The black wire of the camera's power cable is not used.
5. Video Input: Connect the other end of the video cable to the CAM video input interface on the back of the unit. The red line from the video cable connects to the reverse control line of the power line.

Important: If a reversing camera is not installed, do NOT connect the REVERSE/BACK cable. Leave it unconnected. Connecting it without a camera can cause the unit to display incorrectly or enter reverse mode automatically, leading to malfunction.

6. Troubleshooting

This section addresses common issues and their solutions.

6.1. Cannot Boot Normally

1. Wiring Check: Ensure the yellow (B+), red (ACC), and black (GND) wires are correctly connected. Yellow to positive, red to key control, black to negative.
2. Fuse Check: Verify if the fuse on the yellow line is intact. If broken, replace it.
3. Power Test: If wiring and fuse are fine, twist the yellow and red wires together, turn the key, and press the unit's power button. If it boots, the issue might be with the car's original wiring.

6.2. Automatic Shut-down

1. Cable Error: If the blue cable (automatic antenna power supply) is connected to the unit's power cable, an automatic shutdown will occur. Correct the wiring.
2. Unstable Voltage: Test with a stable 12V-5A power supply. If the unit still shuts down, it indicates a problem with the unit.

6.3. Noise Issues

1. Speaker Power: If the original speaker power is too low, noise may occur at high volumes. Avoid excessively high volumes.
2. Grounded Speaker Cable: Ensure speaker cables are not grounded. Connect them directly to the unit's speaker cables.

6.4. Remote Control Not Working

1. Test Method: Use a mobile phone camera to view the remote control's IR light while pressing buttons. If the light doesn't flash, replace the battery.

6.5. Settings Not Saved (No Memory)

1. Wiring Check: Ensure the yellow and red lines are connected correctly (yellow to positive, red to key control). If they are reversed, swap their positions.

6.6. Bluetooth Not Working

Turn on the unit, search for its Bluetooth name on your mobile phone, and click Connect. After connecting, you should be able to answer calls or play music via Bluetooth.

6.7. Product Emits Smoke

Replace the FUSE. If the problem persists, the internal circuit may be burned. Contact support for service.

6.8. Sound Cannot Be Adjusted

1. Reset the unit or unplug and replug the power cord.
2. If the volume knob is broken, it may need replacement.

6.9. Reversing Camera Not Displaying

1. Wiring Check: Verify correct wiring and ensure no wires are missing. Refer to the reversing camera installation method.
2. Camera Fault: If the camera's lamp does not light up when properly wired, the camera may be broken and needs replacement.

6.10. USB Devices Cannot Be Played

Format the USB flash drive to FAT32. Re-download one or two songs and try again. If it still doesn't work, replace the USB flash drive.

6.11. FM Does Not Receive Radio Stations

1. Antenna Connection: Ensure the antenna plug is fully inserted and not disconnected.
2. Station Search: Use the AS button to automatically search for stations, or manually search using the previous/next buttons.
3. If the above steps don't work, unplug the antenna and try inserting a screwdriver or metal strip into the antenna port as a temporary antenna.

6.12. No Sound Immediately After Installation

1. Speaker Cable Short Circuit: Check if any speaker cables are short-circuited or incorrectly connected. Reconnect if necessary.
2. Speaker Cable Count: If your original car wiring only has 2 speaker cables, it may not match the unit. You may need to re-route the original car line. Each speaker requires 2 cables, so 2 speakers need 4 cables.

6.13. No Sound After A While

Disconnect all speaker cables from the unit (do not remove them). Connect an external speaker to the gray and purple wires of the unit's tail line. Try connecting to any green group and check for sound. If there is sound, it indicates a short circuit in the car's speaker line or a damaged speaker. If there is no sound, the unit is broken.

7. User Tips

• Pre-Installation Test: Always test the unit with a 12V power supply before full vehicle installation to confirm functionality and avoid rework.
• Wiring Accuracy: Pay close attention to the wiring diagrams, especially for power and speaker connections, to prevent damage or malfunction.
• CarPlay/Android Auto Setup: For wireless functionality, ensure both Bluetooth and Wi-Fi are enabled on your smartphone before connecting.
