I paired my phone bluetooth with my car (VW) bluetooth. It works fine when I have phone calls, but when I use Google Maps - silence.
Google Maps Settings -> Navigation settings - Play voice over Bluetooth ON
If I set it OFF, I can hear voice from phone directly, but I want to hear it from car bluetooth.
Before I had Windows phone and had the same problem and it was resolved by this advice:
- Go to Settings -> Devices -> Bluetooth
- Click "Advanced"
- Check "use alternate Bluetooth audio connection for Speech"
But I don't see this option in my Android phone.
