Has anyone else had a problem with the google nav volume being WAYYY too loud? I have spotify running over my cars bluetooth and when I am using nav, I have to turn my music way down, almost to the point I can't even hear it, otherwise the nav voice about blows my speakers because it is at least twice as loud. If I turn the media volume on the phone down, music and nav both go down together. Turn media volume up, music and nav both go up together. I never understood why they put media and nav together when it was separate in the early days of android. Is there an app that will separate the nav volume?
