Familiarize yourself with the front panel controls and rear interface ports of the car radio.

• Front Panel: Includes Sound hole, Reset button, Power button, Home button, Return button, Volume Up (+), and Volume Down (-).
• Rear Interface: Ports for Reversing video input, Audio Video Switching, Radio Antenna, GPS Navigation, USB1 (6pin), USB2 (4pin), Power cable, BT Antenna, WiFi Antenna, R-CAM (Reversing Camera Input), and Protocol Box (use only when needed).

4.2 Rear Interface Description and Wiring

Proper wiring is crucial for the correct operation of the car radio. Refer to the diagram below for detailed connections.

Wiring Notes:

• The unit turns on normally when both the yellow (B+) and red (ACC) lines receive 12V positive power simultaneously.
• The yellow (B+) line maintains power to the unit, providing memory function for settings.
• There are 8 speaker cables. Each speaker cable must not be grounded, shared, or touch other lines. Improper wiring can lead to no sound output, distorted sound, or overheating of the unit.

4.3 Reversing Camera Installation Method

Follow these steps to install the reversing camera:

1. Locate the reverse control line (pink wire) on the unit's power line. Connect this line to the 12V positive pole of your car's reverse lamp. The screen will turn blue when reverse is engaged.
2. Locate the CAM video input interface on the rear of the unit.
3. The camera has two plugs: a red plug for power and a yellow plug for video.
4. Connect the red wire of the camera's power cable and the red wire of the video cable together to the positive pole of the reverse lamp. The black wire of the camera's power cable is not used.
5. Connect the yellow video cable to the CAM video input interface on the rear of the unit.
6. The red line extending from the video line should be connected to the reverse control line (pink wire) of the unit's power line.

Important: If a reversing camera is not installed, do not connect the REVERSE/BACK cable to any location. Leave it unconnected. Connecting it improperly may cause the unit to display incorrectly or automatically enter reverse mode, leading to malfunction. If this occurs, disconnect the REVERSE/BACK line immediately to restore normal operation.

5. Operating Instructions

6. Common Problems and Simple Troubleshooting

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 ignition control, black to negative. Incorrect or insufficient connections will prevent booting.
2. Car Wiring Standard: Original car wiring colors may not be standard. Connecting based solely on color might cause damage.
3. Original Car Plug: Do not plug the original car plug directly into the new unit. It may not work or could cause damage.
4. Fuse Check: If the 3 wires are correctly connected but it 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.
5. Repeated Fuse Blowing: If the fuse blows repeatedly, it indicates a short circuit in the unit's protection circuit. The unit requires professional repair. To confirm, connect the yellow and red wires to a 12V battery (positive) and black to negative. If it boots, the car's wiring is faulty. If not, the unit is defective.

6.2 Automatic shut-down

1. Cable Connection Error: If the blue cable (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: Test the unit with a stable 12V-5A power supply. If it still shuts down automatically, the unit is faulty. If not, replace your car's power supply.

6.3 Noise Issues

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

6.4 Remote control cannot be used

Test Method: Use your mobile phone camera to point at the remote control's light and press a button. If the light doesn't illuminate, replace the battery. If it lights up, the remote control is working correctly.

6.5 Settings cannot be saved (no memory)

1. The yellow (B+) and red (ACC) lines are connected together (yellow to positive, red to key control).
2. The yellow and red wires are reversed (simply 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 can make calls or play music via Bluetooth.

6.7 Product emits smoke

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

6.8 Sound cannot be adjusted

1. Reset the unit or unplug and replug the power cord.
2. The volume knob is broken and needs to be replaced.

6.9 Reversing camera does not display

1. Wrong or missing wiring: Refer to section 4.3 for correct camera connection method. Ensure all accessories (camera, power cord, video cable) are present and correctly connected.
2. Broken Camera: If the lamp connected to the camera does not light up when properly wired, the camera is likely 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. The antenna plug is not fully inserted, or the antenna/line is disconnected.
2. Search for stations by pressing the AS button for automatic search, or use the forward/backward 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 test.

6.12 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. Check the following:

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 must lead to 2 speaker wires.

6.13 No sound after a while

Disconnect all speaker cables from the unit (do not remove them). Find an external speaker and connect it to the gray and purple wires of the unit's tail line. Connect any green wire to ground. Test 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.

7. User Tips

• External Display Connection: If connecting external screens (e.g., headrest monitors) and they are not functioning, double-check all wiring and configuration settings. Ensure the video output from the car radio is correctly connected to the input of the external screens, and that the external screens are powered on and set to the correct input source.
• Regular Software Updates: Keep your Android system updated to ensure optimal performance and compatibility with new apps and features.
• Screen Protector: Consider applying a screen protector to the display to prevent scratches and prolong its lifespan.

8. Maintenance

• Cleaning: Use a soft, dry cloth to clean the display and exterior of the unit. Do not use abrasive cleaners or solvents.
