No prob. Ya, after you plug the phone in the USB and you run Pandora, it should pop up on either the BMW Apps list or the Radio section in idrive. Make sure Pandora on the device shows that you are connected to to the idrive when you run Pandora. There will be a "BMW" on the phone and it will say "Connected".
If all else fails, try rebooting the external device and the idrive (hold in volume/mute button for ~30 seconds). I had a problem a few days ago where my device apps (iPod, MOGG and Pandora) weren't playing audio through the car's stereo. I just rebooted the idrive and it worked.
