Setup and Installation

Operating Instructions
- Power On: Turn on your car ignition and car radio.
- Select CD Changer Mode: On your car radio, select the CD changer mode (often labeled "CD," "CDC," "AUX," or "Source"). The radio will recognize the Bluetooth adapter as a CD changer.
- Pairing Your Device:
- On your smartphone or Bluetooth-enabled device, go to the Bluetooth settings.
- Search for available devices. The adapter should appear as "BlueMusic" or a similar identifier.
- Select "BlueMusic" to pair. No PIN is usually required.
- Once paired, your device will automatically connect to the adapter when the radio is in CD changer mode and Bluetooth is enabled on your device.
- Music Playback:
- Start playing music on your paired device. The audio will be streamed through your car's speakers.
- Track Control: You can control track playback (next/previous track) directly from your car radio's buttons or steering wheel controls, if supported by your radio model.
Maintenance
The BlueMusic Bluetooth Audio Adapter requires minimal maintenance. Keep the adapter and its connections free from moisture and extreme temperatures. No user-serviceable parts are inside.
Troubleshooting
- No Sound:
- Ensure the radio is set to CD changer mode (AUX/CD/CDC).
- Verify your device is successfully paired and connected to "BlueMusic".
- Check the volume levels on both your device and the car radio.
- Confirm all connections, especially the ground wire, are secure.
