auouymous, thanks for the info. I did not run the a2dp runfirst yet. I also got the impression that choosing the audio to play through a2dp would be very limited --- and likely would not work with streaming radio like lastfm. Oh well, I can still return the sony receiver.

Essentially this would work the same as using a2dp headphones, except I'm sending to my stereo. Does anyone have any first hand experience with a2dp headphones with the N810?

As far as the bluetooth modem goes, I am not familiar with that so I googled it and I don't really see how it would resolve my issue. The one I found on amazon needed dial-up with it and I don't even have home phone ---- thanks for the suggestion though.
