How does the One X handle Bluetooth and aux audio?

[exwifeusesiphone]

I'm thinking of returning my Galaxy Siii because the Bluetooth functionality is FUBAR.

When I get a call in the car, it switches the audio to the line-out because I have a stereo cable plugged in, so I can't hear my caller, but they can hear me because my car Bluetooth mike picks up my voice.

How does the One X handle this situation? Can I use Bluetooth and still have a stereo cable plugged in for audio apps?

My One X handles this in the manner you wish. If I have an audio cable connected to my car stereo's audio in (aux) and I have a bluetooth hands free device paired, when a call comes in the music cuts off and the bluetooth headset (mic and speaker) take over. Once the call ends, the music starts again through the car stereo.
