Setup and Installation

Before Installation

Before proceeding with the full installation of the product into your car, it is highly recommended to test the unit first. Due to potential impacts during transit, the product may be affected. Please test the machine thoroughly before permanent installation.

Rear Interface Description and Wiring

The following diagram and table detail the connections for the car multimedia player. Ensure all connections are secure and correct to prevent damage and ensure proper functionality.

Important Notes:

• When the yellow line B+ and the red line ACC have a 12V positive power at the same time, the unit can be turned on normally.
• The yellow line B+ keeps the power on and the machine has a memory function.
• For speaker connections, ensure each of the 8 speaker cables is not grounded, shared, or touching other lines. Incorrect wiring can lead to no sound output, distorted sound, or overheating of the unit.

CANBUS Connection

The CANBUS system allows the head unit to communicate with your car's internal systems. The connection method varies slightly depending on whether your car is a high-end or low-end model.

• For High-End Models: Connect the CANBUS box.
• For Low-End Models: Disconnect the CANBUS box.
• Attention: If both the CANBUS box and the black buckle are connected simultaneously, it may cause the radio to fail to shut down after the car is turned off.

Reversing Camera Installation

Proper installation of the reversing camera ensures automatic display of the rear view when reversing.

1. Display Position (A): This indicates where the rearview image will be shown on the head unit screen.
2. Camera Power Supply (B): Connect the camera's power supply to the positive and negative poles of the car's tail light. This ensures the camera powers on when the car is in reverse.
3. Camera Position (C): Install the camera at the rear of the car.

Wiring for Reversing Camera:

• Find the reverse control line (pink wire) on the unit's power line. Connect this line to the positive 12V pole, and the screen will turn blue when reversing.
• Locate the CAM video input interface at the back of the unit.
• The camera has two sockets: connect the red socket to the power cable, and the yellow socket to the video cable.
• Twist the red wire of the power cable and the video cable together, connecting them to the positive pole of the reverse lamp. The black wire of the power cable is not used.
• Connect the other end of the video cable to the CAM video input interface on the back of the unit.
• The red line coming out of the video line connects to the reversing control line of the power line.

Important: If the reversing camera is not installed, do not connect the REVERSE/BACK cable. Leave it unconnected. Connecting it without a camera may cause the unit to display improperly or enter reverse mode incorrectly, leading to malfunction. If this occurs, disconnect the REVERSE/BACK line immediately.

Troubleshooting

This section addresses common issues and provides solutions. If you encounter a problem not listed here, please consult the PDF user manual or contact customer support.

1) Cannot boot normally

1. Wiring Check: Ensure the yellow (constant 12V), red (ignition switch), and black (ground) wires are correctly connected. Incorrect or insufficient connections will prevent booting.
2. Original Car Wiring: Do not connect the unit's wiring directly to the original car's wiring by color alone, as car wiring colors may not be standard. Incorrect connections can cause damage.
3. Original Car Plug: The original car plug cannot be directly plugged into the new unit. Even if it fits, it may not work or could burn out.
4. Fuse Check: If the three main wires are correctly connected but the unit doesn't boot, check the fuse on the yellow line. If the fuse is intact, twist the yellow and red wires together, turn the key, and press the unit's power button to test.
5. Repeated Fuse Burning: If the fuse burns every time it's replaced, it indicates a short circuit in the unit's protection circuit. The unit may require professional repair. If the unit still doesn't boot after verifying all connections and fuses, connect the yellow and red wires to a 12V battery (or 12V power supply) and the black wire to negative. If it boots, the car's wiring is faulty. If it doesn't boot, the unit is defective.

2) Automatic shut-down

1. Cable Error: If the blue wire (automatic antenna power supply) is connected to the unit's power cable, it will automatically shut down. Follow the correct wiring method.
2. Unstable Voltage: Find a stable 12V-5A power supply and re-test. If the unit still shuts down automatically, the unit is faulty. If it doesn't, the power supply is the issue.

3) There is noise

1. Low Speaker Power: If the original speaker power is too low, increasing the unit's volume will cause noise. When replacing speakers or listening to music, ensure the volume is not excessively high.
2. Grounded Speaker Cable: If a speaker cable is grounded, connect the iron speaker cable directly to the unit's speaker cable.

4) Remote control cannot be used

Test Method: Use your mobile phone's camera to check the remote control. Point the remote control at the camera and press a button. If the remote control's light doesn't illuminate on the phone screen, it has no power (replace battery). If it lights up, the remote control is working correctly.

5) Settings cannot be saved (no memory)

1. The yellow (constant 12V) and red (ignition switch) wires are connected together. They should be separated (yellow to positive, red to key control).
2. The yellow and red wires are reversed. Correct their positions.

6) Bluetooth not working

Turn on the unit, then use your mobile phone's Bluetooth function to search for the unit's Bluetooth name and click 'Connect'. After connecting, you should be able to make calls and play music via Bluetooth.

7) The product emits smoke

Replace the FUSE. If the problem persists, the internal circuit is burned. After-sales service is required.

8) The sound cannot be adjusted

1. Reset the unit or unplug and re-plug the power cord.
2. If the volume knob is broken, it needs to be replaced.

9) Reversing camera does not display

1. Wrong or Missing Wiring: Refer to the "Reversing Camera Installation" section for correct wiring.
2. Broken Camera: If the camera's light does not illuminate when properly wired, the camera is broken and needs replacement.

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.

11) FM does not receive the radio station

1. The antenna plug is not fully inserted, or the antenna is disconnected/faulty.
2. Search for stations: Press the 'AS' button for automatic search, or use the 'before'/'after' buttons.
3. If the above doesn't resolve the issue, unplug the antenna plug and insert a screwdriver or metal strip in its place to act as a temporary antenna.

12) No sound right after installation

The unit is tested before shipment. If there is no sound, it's usually a wiring error or a short-circuited original car speaker wire. To check:

1. Check if the speaker cable is short-circuited and connected. Reconnect if there's a short circuit.
2. Verify the number of speaker cables. If your original car has only 2 speaker cables, but the unit requires 4, you need to re-route the original car line. One speaker needs 2 speaker wires; two speakers need 4 speaker cables.

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 tail lines of the unit. Connect any group to green and check for sound. If there is sound, the car's speaker line is short-circuited or the speaker is damaged. If there is no sound, the unit is broken.
