Just got my ipod adapter. Using it on an iphone 3gs.

Issue I'm having is that when I'm listening to the music, and I get a phone call on the bluetooth - the music doesn't come back on once I've disconnected the phone call.

The interface goes back to ipod, it shows the song and everything, but no music.

I have to unplug the iphone and plug it back in to get it working.

Any ideas as to what's wrong?
