Streaming Audio From iPhone

Just picked up my new F32 Saturday, which has Enhanced Bluetooth. Bluetooth connects great, plays iTunes music no problem, and can make phone calls. This morning I tried to stream "non-iTunes" audio (Tune In Radio), and I just couldn't get it to work over the bluetooth connection. The phone kept reverting to playing the last selected iTunes playlist.



Can I stream non-iTunes audio over bluetooth? Do I need to plug the phone in to do this? If not - any idea what I'm doing wrong?
