When my wife rides with me we have intercom connections plus each of us has a bluetooth connection to the bike radio.  The radio has 2 BT connections which allows this.  We have the intercom overlay feature on so we can hear music when we have an intercom connection.  The bike does not allow for muting by connection.  I'd like to have the ability to turn the BT connection off so if one of us doesn't want to hear the radio we can do so without losing the intercom.
