Adjust Bluetooth volume?

[javis20]

Is there a way to adjust the disparity between Bluetooth device volume and radio volume. My Bluetooth phone is much quieter. For instance, when I switch from Spotify, on my phone, to the cars radio the volume is outrageously loud. Car is a 2011 with iDrive.

Is the volume on your phone turned down, try setting the radio volume then switching to your phone and then turn the volume up on your phone.
