Audio stream
The differences between the iPod kit plugged in and streaming bluetooth are that you don't see album artwork, it takes a few seconds for the title and artist to pop up (nearly instant with iPod kit) and most importantly, you are not able to scroll through the songs or playlists. Simply whatever playlist your iPhone is set to on A2DP it will start playing. So I just make sure my phone is on my playlist and then I shuffle the songs.
I am 99% sure that the UMI interface for the 2009's have the same exact functionality, although I'm not 100% positive.
