I matched the bluetooth of my phone with the bluetooth of my car (VW). It works well when I have phone calls, but when I use Google Maps: silence.
Google Maps settings -> Navigation settings – Play voice-over
If I deactivate it, I can listen to the voice of the phone directly, but I want to hear it from the Bluetooth of the car.
Before having Windows Phone, I had the same problem and it was solved with this advice:
- Go to Settings -> Devices -> Bluetooth
- Click on "Advanced"
- Check "use alternative Bluetooth audio connection for voice"
But I do not see this option on my Android phone.
