Thanks for the response. All the topics I've read up until this point have sort of indicated what you have confirmed, that the bluetooth is separate. It was just what sparked the thought.
Are there RB5s that are newer than the RB5 in the 2011? I ask because, the units in the 2011 had issues where gracenote was screwed up, sirius traffic was not available, and playing songs for the ipod connection caused them to end 4 seconds early. There are other quirks as well, I was just curious if I could pop-in a newer revision RB5... apps would have been nice though (as I understand that's what the 'A' designates on the 8.4AN?).
