I discover this accidentally when I plugged in the auxiliary jack from the phone to my wife's toyota Sienna.
I was listening to some music on my Moto X through the AUX jack via the headphones. A phone call can't in. I answered it thinking I would be on speaker but something different happened.
The audio was coming through the car's speakers but the mic remained open on the phone. I thought the mic would not be on because of the audio jack.
In fact, open mic works as well.
So plug in your phone in your AUX jack and enjoy hands free calling and hearing it clearly through your car's step system.
