My 2002 has AVC, Automatic Volume Control, goes up and down with the speed. I think most with the premium audio have itThis may be off your subject in a way , but I do have a question for the group. Back on my 2003 GL 1800 it seemed to me the volum automaticly rose with the speed of the bike (I think ?) Now my 2010 does not do this and I must use head set or jack up the volume to like 26 to hear it , in turn this May blow the speakers ?? Question, am I missing setting a sound controll or do these Wings no longer have auto volum ?
