4. Troubleshooting

This section addresses common issues you might encounter with your car MP3 player.

4.1 Cannot Boot Normally

1. Incorrect Wiring: If only two of the three main wires (Yellow, Red, Black) are connected, the unit will not start. Ensure Yellow is connected to the positive pole, Red to the key control line, and Black to the negative pole. Incorrect or insufficient connections will prevent booting.
2. Incompatible Wiring: The original car wiring and unit wiring may not match in color or standard. Connecting them incorrectly can cause damage or prevent operation.
3. Original Car Plug: The original car plug cannot be directly inserted into the new unit. Even if it fits, it may not work or could cause damage.
4. Fuse Issue: If all three 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 power button to test.
5. Repeated Fuse Blowing: If the fuse blows repeatedly, do not replace it again. This indicates a short circuit in the unit's protection circuit. The unit requires professional repair. Before returning, ensure you have followed the test method (connecting Yellow/Red to 12V positive, Black to negative) to confirm the unit's functionality. If it boots during this test, the car's wiring is likely incorrect.

4.2 Automatic Shut-down

1. Cable Connection Error: If the blue antenna power cable is connected to the unit's power cable, it will cause automatic shutdown. Follow the correct wiring diagram.
2. Unstable Voltage: Test the unit with a stable 12V-5A power supply. If it still shuts down automatically, the unit is faulty. If it works correctly with the test power supply, replace your car's power supply.

4.3 Noise Issues

1. Low Speaker Power: If the original speakers have low power, increasing the unit's volume may cause noise. Avoid excessively high volumes when using or replacing speakers.
2. Grounded Speaker Cable: If a speaker cable is grounded, connect the iron speaker cable directly to the unit's speaker cable.

4.4 Remote Control Cannot Be Used

1. Test Method: Use your mobile phone camera to check the remote control. Point the remote at the camera and press a button. If you see a light on your phone screen, the remote is working. If not, replace the remote's battery.

4.5 Settings Not Saved (No Memory)

1. Ensure the yellow and red wires are connected correctly (Yellow to positive, Red to key control).
2. If Yellow and Red wires are reversed, simply swap their positions.

4.6 Bluetooth Not Working

Ensure the unit is on, search for "SWL-BT" on your phone's Bluetooth settings, and connect. If issues persist, try resetting the unit or your phone's Bluetooth.

4.7 Product Emits Smoke

Immediately replace the FUSE. If the problem is not resolved, the internal circuit may be burned, requiring after-sales service.

4.8 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.

4.9 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.

4.10 FM Does Not Receive Radio Station

1. Ensure the antenna plug is fully inserted and not disconnected.
2. Use the AMS/APS button to automatically search for stations, or use the previous/next track buttons to manually tune.
3. If the above steps don't work, unplug the antenna plug and insert a screwdriver or metal strip into the antenna port as a temporary antenna for testing.

4.11 No Sound Immediately After Installation

This usually indicates a wiring error or a short-circuited car speaker wire. Check the speaker cables for shorts and reconnect. If only two speaker cables are present, and the original car line requires four, you may need to re-route the car's wiring to provide four speaker cables (two per speaker).

4.12 No Sound After A While

Disconnect all speaker cables from the unit. 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 faulty.
