When my phone is connected via bluetooth in my car, I'd like the Phone app to be the only one to output through the car's sound system, and let the rest going through the phone's speaker.
Right now the whole phone's audio goes through the car's sound system which prevents me from, for instance, listening to music from a USB key (plugged in the car) and listening to Google maps (running on my phone) instructions at the same time. I have to chose between the bluetooth and the USB media.
- Phone: Android 5.0.1 on Nexus 4
- Receiver: Volvo Sensus Connect (I think)
