Does any else think the nav voice level is very low,we hav it turned up all the way.On other cars i have had the voice was adjustd by the radio volume ***.This goes to volume 7 not loud,don't turn the radio on or people talking in the car.....

 

Did you try adjusting via Menu / Setup / Voice? There are several nav voice options with volume adjustments. As you increase or decrease volume it says something so you can see how loud it will be. I actually have them all set to OFF.
