Streaming vs calling

[ukrkoz]

OK, I added Scosch BT adapter to 3.5mm Aux input in my car.
Set up phone and now it streams fine.
Dilemma is: I also have factory BT hands free in my car. No streaming, just calls.
Now, calls do not go through the phone, though BT logo shows on the head unit, confirming phone is connected to the HU.

I have 2 options in BT settings for Scosch adapter:
CALL AUDIO use for phone audio
MEDIA AUDIO use for media audio.

What do I use for streaming ONLY so that calls go through the factory BT hands free?

Media audio, which is what an audio stream is. (No guarantee, though, that the factory BT won't show as both to the phone, so you won't get BT streaming. But you might. Unfortunately, even if there were some standards, which there aren't, car manufacturers seldom follow any standard they didn't create themselves. So Ford follows Ford standards, Chevy follows Chevy standards, etc. And Scosch? Who knows what standards they follow? Probably the same ones your Note 2 does. Which may be totally different then what your car BT does. Or it might not be. Only way to tell is to set it to media audio and see if media audio [music] comes through the aux input.)

Normally media audio is for streaming. There are a few apps that use the call audio like Skype, Google Voice Search, etc...
