I'm having Bluetooth issues as well...my phone connects fine, but after hanging up a call something happens where it drops the connection and the only way to get it back is to turn off bluetooth on the phone and turn the stereo off, then turn bluetooth back on the phone and then turn the stereo back on. Even though the connection gets dumped the stereo is not recognizing it.
When streaming music or podcasts the behavior is that the phone is streaming, a call is placed (or comes in) which pauses the stream and then when the call has ended the stream should resume. In my case I get the dreaded "force close" vibrate series (vibrate, pause, then 2 vibrates) but I never get a force close message. The content that was streaming attempts to stream and then stops and the connection is gone at that point.
I'm very frustrated at this point as I have taken the time to reinstall everything from scratch, wiping the phone to factory, deleting dalvik cache, regular cache, wiping, etc. from recovery. It worked last night in testing and it worked initially this morning. And then a little later this morning it went back to not working.
