So this morning, i was able to sit in the car (with the phone locked) and connected to bluetooth, and say, "Siri, call John Smith". It worked like clock work; perfect, except that once the call was made, Siri never would revert to the locked screen. It stayed on the siri screen. I tried to make some adjustments as to Voice playback etc. I'm not sure what I've done. Now when I perform the same action in the car, it makes the call fine. The problem is that even after the call is discontinued, it keeps my audio system locked onto phone (as if it's using the phone) and lt keeps it from reverting to my stereo. The minute I shut off Hands Free, the radio starts playing. Any idea what settings I screwed up? I know it works, because it worked this morning.
