From one Music fan to another, please STOP Adjusting the bluetooth volume of my favorite song, for voice navigation!!! That is soooo annoying. I even tried to set the voice navigation to come through my phone instead, and Waze still turned down my bluetooth music.. ughhh. SOLUTIONS:: Either PAUSE the music, when doing the voice navigation, or just do the voice navigation, leaving bluetooth volume alone. You DON'T need to touch the bluetooth audio at all. Just let it mix naturally. If the user can't hear it, then can turn down their stereo volume manually if needed. This is a simple fix. Just remove the code, that lowers the volume of bluetooth. simple. Don't TOUCH MY MUSIC and FAVORITE SONGS PLEASE!!!! Thanks :)
