2012 Bayswater with nav.
While using turn-by-turn direction the voice directions are so low I can't hear them without blasting the radio volume.
I've traversed all the setup items but find nothing for voice volumes.
Can this be changed?

 

This is a little BMW feature that has always annoyed me. You can only adjust the navigation voice volume WHILE IT IS SPEAKING!! When the radio fades out and you should be hearing turn directions you need to be ninja quick and reach for the volume **** and turn it up. This will not adjust the radio volume but only the nav volume. It would be so much better if there was a setting in the menus somewhere that you could set the volume offset from the current radio volume but, alas, there is not. Just gotta hit that volume **** with the quickness!!
