7. Troubleshooting

This section addresses common issues you might encounter with your car stereo. If the problem persists, please contact customer support.

Q: Is the product always on? Car flameout products still working?

A: Please check your wiring. The red wire needs to be connected to your ACC (car key hole) to ensure the machine turns off with the car. The yellow wire needs to be connected to the positive pole of the battery, and the black wire to the negative pole. Correct connections are crucial for normal operation.

Q: Cannot use the memory function? Cannot save channels?

A: If the ACC line (Red wire) and the B+ line (Yellow wire) are reversed during installation, the product will have no memory function after the power is off. Please ensure these wires are connected correctly as per the wiring instructions.

Q: Cannot connect to Bluetooth?

A: Please delete any existing Bluetooth records on both your mobile phone and the car stereo. Then, re-match the connection. When connecting a new Bluetooth device, previous records may need to be cleared.

Q: Music is playing but cannot hear sound?

A: Check if FM radio is currently playing. If so, turn off the FM function to hear other audio sources.

Q: Does it support external devices compatible with subwoofers? How can I connect it?

A: Yes, it supports external subwoofers. Connect the subwoofer directly to the L-OUT and R-OUT ports, or use an adapter and connect its lead to the B harness.

Q: People cannot hear me during Bluetooth calls (microphone issue)?

A: While you can hear them perfectly through the speakers, if others report difficulty hearing you, the microphone may be experiencing issues. Ensure the microphone is not obstructed and is positioned optimally. If the problem persists, contact support.

Q: Radio has static and distortion?

A: Ensure all antenna connections are secure and properly installed. Poor antenna signal or faulty connections can lead to static and distortion. Verify that the antenna is correctly plugged into the unit.
