On my Model 3, during the navigation directions the Radio/music that is playing is not being muted or even volume lowered so that I can hear navigation direction. I am not sure if there is a setting some here. All cars I had sofar automatically mute the Radio/Music during navigation directions. (even android phone does it too). My older Toyota even more clever in reducing the volume of Radio as well as giving Directions only on Drivers side speakers so driver can hear it clearly and others not disturbed much. Please post if someone found a way to do that. Thanks in advance.
