Google Maps turn-by-turn navigation voice directions do not broadcast through bluetooth devices. I use a Jawbone New Era headset or a Motorola HX550 headset voice instructions to not come through either device. If I un-pair the device and turn off bluetooth option voice commands can be heard through the speaker on my LG G4 smartphone. This is not the optimal solution in a hands free regulated environment.
Please suggest settings that will make bluetooth function with Google Maps Turn-By-Turn Navigation.
