3.1 Rear Interface Description and Wiring

The following diagram illustrates the rear interface and wiring connections for the car stereo. Ensure all connections are made correctly to prevent damage and ensure proper functionality.

Power Plug Connections:

• White / White/black striped: Front speaker (Left/Right)
• Gray / Gray/black striped: Front speaker (Left/Right)
• Green / Green/black striped: Rear speaker (Left/Right)
• Purple / Purple/black striped: Rear speaker (Left/Right)
• Black (thick): GND (Ground Wire/B-)
• Yellow: BATTERY (Constant Power Supply +12V)
• Red: ACC (Ignition Switch)
• Orange: ILLUMINATION (Illuminate Backlight)
• Pink: REVERSE (Reversing camera control line)
• Brown: KEY2 (Steering Wheel Control-2)
• Orange/black striped: KEY1 (Steering Wheel Control-1)
• Blue: ANT (Auto Antenna Power)

Important Wiring Notes:

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

3.2 Reversing Camera Installation

Follow these steps to install the reversing camera:

1. Locate the reverse control line (pink wire) on the unit's power harness. Connect this line to a 12V positive power source. The screen will turn blue when activated.
2. Find the CAM video input interface at the back of the unit. Identify the positive and negative terminals of the backup light.
3. The camera typically has two sockets: a red socket for power and a yellow socket for video. 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.
4. Connect the other end of the video cable to the CAM video input interface on the back of the unit. The red line extending from the video cable connects to the reverse control line of the power harness.

Caution: If the reversing camera is not installed, do not connect the REVERSE/BACK cable to any other location. Leave it unconnected. Otherwise, the unit may not display correctly or may automatically enter reverse mode, causing malfunction. If this occurs, disconnect the REVERSE/BACK line immediately.

3.3 General Installation Tips

• Ensure the antenna plug is fully inserted for optimal radio reception. If the antenna is disconnected or the line is faulty, radio reception will be poor.
• For USB devices, format the USB flash drive to FAT32 and re-download media files if playback issues occur.
• If your vehicle has a CAN-Bus system, ensure it is correctly integrated for features like climate display and parking sensors.

6. Troubleshooting

This section addresses common issues you might encounter. For more complex problems, please refer to the official user manual PDF for further details or contact customer support.

6.1 Common Problems and Solutions

1. Cannot boot normally:
   • 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 incomplete connections will prevent booting.
   • Check the fuse on the yellow line. If it's blown, replace it. If the fuse is fine, try twisting the yellow and red wires together, then turn on the key and press the power button.
   • If the unit repeatedly blows fuses, there might be a short circuit in the protection circuit. Professional repair is needed.
2. Automatic shut-down:
   • If the blue (automatic antenna power supply) cable is connected to the unit's power cable, an automatic shutdown will occur. Correct the wiring.
   • Unstable voltage can cause automatic shutdowns. Test with a stable 12V-5A power supply. If the issue persists, the unit may be faulty.
3. There is noise:
   • If the original speaker power is too low, noise may occur at high volumes. Reduce volume or consider speaker replacement.
   • If a speaker cable is grounded, disconnect it and ensure it's not touching any metal.
4. Remote control cannot be used:
   • Test the remote control by pointing it at a mobile phone camera and pressing a button. If the phone camera shows a light, the remote control has power. If not, replace the battery.
5. Settings cannot be saved (no memory):
   • Ensure the yellow and red lines are connected correctly (yellow to positive, red to key control). If they are reversed, swap their positions.
6. Bluetooth not working:
   • Turn on the unit, search for its Bluetooth name on your mobile phone, and connect.
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:
   • Reset the unit or unplug and replug the power cord.
   • If the volume knob is broken, it needs to be replaced.
9. Reversing camera does not display:
   • Check for incorrect or missing wiring as described in Section 3.2.
   • If the camera's lamp is not lit when properly wired, the camera itself may be broken and needs replacement.
10. USB devices cannot be played:
    • Format the USB flash drive to FAT32. Re-download songs and try again. If it still doesn't work, replace the USB flash drive.
11. FM does not receive radio stations:
    • Ensure the antenna plug is fully inserted.
    • Perform an automatic station search (press AS button).
    • If issues persist, unplug the antenna and try inserting a screwdriver or metal strip as a temporary antenna to check if the problem is with the antenna itself.
12. No sound right after installation:
    • Check if speaker cables are short-circuited or incorrectly connected. Reconnect if necessary.
    • Verify the number of speaker cables. If your original car has only 2 speaker cables and the unit requires 4, you may need to re-route the car's wiring.
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. 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

• CAN-Bus Integration: For vehicles like the Skoda Octavia, the unit integrates well with CAN-Bus, displaying climate information and parking sensors. Active parking lines can be enabled in the 'Car info' settings.
• Screen Not Turning Off: If the screen remains on after turning off the car (e.g., in a 2005 Polo), you might need to remove a specific cable from the control unit to resolve this.
• Sound Quality: While the unit offers many features, some users note that the sound quality might not match premium stock systems. Upgrading audio processor chips (e.g., TDA7313, TDA7850) might improve the audio experience.
• USB Ports: The unit includes USB ports for media playback and connectivity. Ensure USB drives are formatted to FAT32 for compatibility.
• Hidden Menus/Board Computer: For Opel Zafira B users, check if the hidden menu for temperature display remains active after installing the car stereo.
• Video Playback: If videos are blocked by the system, check settings for options to enable video playback while driving (use with caution and adhere to local laws).
