If you restart your mobile device or reconnect it via Bluetooth, the sound source you selected with the Music Center application changes from My Library to Audio in.
This will prevent the sound of your mobile device from being output from the car stereo (XM-GS6DSP).
To solve this, check the following:
- Open the Music Center application.
- Select your mobile device from Speaker & Group.
- Change the sound source from [Audio in] to [My Library].
- Select a music file for playback.
