Youch... gets pricey to add Sirus to the Denon. I guess I assumed that part of the feature pack upgrade made it possible to connect to Sirius without the external hardware. (which was maybe naive as it's called 'satellite radio' but I thought you could get it through the ethernet connection.)

What does the feature pack upgrade actually give you in the Denon if you still have to have an external tuner? Remote control of station selection from the Denon GUI, but only coupled with a device like this?
