I've only played with Bluetooth a few times but felt the audio quality was bad so never really used it. Today I had it on unknowingly and used Google maps. Turns out Google maps turn-by-turn voice navigation interrupts the music to announce upcoming turns -pleasant surprise! With the standalone Google maps app, even if your screen is off and phone locked, Gmaps still provides a text prompt to ur phone and audio guide via radio for upcoming turns.
