I recently moved from Hawaii to Georgia. While I was in Hawaii, I was able to play music from my Spotify app through my car stereo, via aux jack, and have the Google Navigation app play through my Jabra Bluetooth speaker that's clipped to my visor. When I got to the mainland, when I tried playing both at the same time, the Spotify app would pause and the navigator would play through the car speakers. It wouldn't be a problem normally, but it is barely audible through the car speakers. Does anyone know how I can get the navigation app to only play through the Bluetooth and not through the aux?
