Dave L Posted May 24, 2004 Report Share Posted May 24, 2004 For those of you with the Bose radio, is the Automatic Volume Control (AVC) functionality obvious? This may seem like a dumb question but there seems to be no difference if mine is turned on or off. The way I am testing it is this: Driving down the road, I set the radio (or CD) at a moderate level with windows up and verify that AVC is turned on. I then roll down the windows. The volume out of the speakers doesn't appear to change with the windows up or down, the sound becoming masked by the wind noise. I've had this into the dealer twice. Both times they sent the head unit out for repair. When it has come back, they report problem fixed yet there seems to be no change. Before I go back to them, again, I wanted to check with the experts here and make sure my test procedure is valid and see if there are any other suggestions. I also wonder if the problem is not with the head unit but with the microphone input that picks up the ambient noise in the car. Does anyone know if this is integral to the head unit, shared with the On-star mike or an independent mike input? Thanks, Dave Link to comment Share on other sites More sharing options...
