Word is that the standard stereo on all cars for the new year will include those features. So, it may be that this is what you've heard, or what someone has interpreted to mean that the HK system will include them, and I don't think that's a valid conclusion to draw.
However, it's hard to imagine that the HK system wouldn't include those features, anyway, so I think you're probably safe in this assumption. Perhaps HK can tell you? You might visit their web site and see if you can contact them for details-- I'm curious to know, too. I'm waiting for the HK system regardless, as the upgraded sound is more important to me than sat or aux input, but I'd certainly like to know that I could use a spiffy Apple iPod with the HK one day.
