• Software Updates: Periodically check the manufacturer's website for any available software updates to improve performance and add new features.

8. Troubleshooting

8.1. Common Problems and Solutions

1. Cannot boot normally:
   • Check power wiring: Ensure yellow (B+), red (ACC), and black (GND) wires are correctly connected. If only two wires are connected, the unit will not power on.
   • Verify fuse: Check if the fuse on the yellow wire is broken. If not, twist the yellow and red wires together, turn on the key, and press the unit's power button.
   • If the unit still doesn't boot, test with a 12V battery by connecting yellow/red to positive and black to negative. If it boots, the car's wiring is faulty.
2. Automatic shut-down:
   • Cable error: If the blue (automatic antenna power supply) cable is connected to the unit's power cable, it will shut down automatically. Correct the wiring.
   • Unstable voltage: Test the power supply with a stable 12V-5A source. If it still shuts down, the unit may be faulty.
3. There is noise:
   • Original speaker power too small: Reduce volume when replacing speakers or listening to music.
   • Speaker cable grounded: Ensure speaker cables are not grounded.
4. Remote control cannot be used:
   • Test remote: Use a mobile phone camera to check if the remote control's IR emitter lights up when a button is pressed. If not, replace batteries.
5. Settings cannot be saved (no memory):
   • Yellow and red wires connected together: Separate yellow to positive, red to key control.
   • Yellow and red reversed: Change their positions.
6. Bluetooth not working:
   • Ensure Bluetooth is enabled on both the unit and your phone. Search for the unit's Bluetooth name and connect.
7. The product emits smoke:
   • Replace the FUSE. If the problem cannot be solved, the internal circuit has been burned. After-sales service is required.
8. The sound cannot be adjusted:
   • Reset the unit or unplug/replug the power cord.
   • Volume knob is broken: Replace the knob.
9. Reversing camera does not display:
   • Wrong or missing wiring: Check the camera connection method (Figure 7). Ensure the camera's video port is inserted into the "CAMIN" car radio port.
   • Broken camera: If the camera's light is not lit when properly wired, the camera may be faulty.
10. USB devices cannot be played:
    • Format the USB flash disk to FAT32. Re-download files and try again. If it still doesn't work, replace the USB flash drive.
11. FM does not receive radio stations:
    • Antenna plug not fully inserted or disconnected.
    • Search for stations using the AS button or manual tuning. If issues persist, unplug the antenna and insert a screwdriver or metal strip into the antenna port as a temporary antenna.
12. No sound right after installation:
    • Check speaker cable for short circuits. Reconnect if necessary.
    • Verify the number of speaker cables matches the original car wiring. If only 2 speaker cables are present but 4 are needed, re-route the car's wiring.
13. No sound after a while:
    • Disconnect all speaker cables from the unit. Connect an external speaker to the gray and purple wires of the tail line. If there is sound, the car's speaker line is short-circuited or the speaker is damaged. If no sound, the unit is broken.
14. Restore to factory settings:
    • If CarPlay, Android Auto, or Mirrorlink connection is abnormal, go to "Basic Settings" > "Restore Factory" and select "YES". If a reset button is on the panel, press it to restore settings.
