I recently switched from Windows Phone, and on my old phone, voice navigation would break through as a Bluetooth "call" in my car, regardless of what source the stereo was set to (HD radio, USB, etc.); on my new Galaxy S8+, it seems that voice navigation only works when the stereo is playing Bluetooth media from the phone; how do I get the directions to break through as a notification/call rather than treating it like music? Haven't found a relevant setting yet, but it's quite annoying that I can't get voice directions while listening to the radio... I know Waze has an option to play audio over the phone's speaker, which is kind of a clunky work-around, but better than nothing. Surely there's some way of getting this to work properly though?
