I appreciate how I can link my iPhone with my Mazda6, but have a few frustrations I'm hoping people can help me with.

I would like to be able to have it nice and quiet when there are others in the car, but still have the Bluetooth come through with driving directions or phone calls. What I currently do is mute the radio when someone else is in the car. Should I get a call, it comes through the car system, but once I end the call the radio comes on again at full volume. When I try and use the phone for directions it will start off using the phone speaker, then just go silent. Very frustrating, and I assume others must have figured out a way around this, so I thought I'd ask.

Also: is there any way to turn the music options completely off other than to mute them?

Thanks for any help/guidance you can give me!
