Ah...that would make sense why it would test out close to the same as the RadioShack craptastic. However, using this software, would you really want directional? Personally, the reason I wanted this software in the first place is because when I was showing my carpc off to my brother, the first thing he said was "play michael bolton" and I had to tell him my carpc couldn't do that.
I'm not sure that when you say directional, that converts to unidirectional, but what I have found with the mic by itself is, because of the tubular design, if you move to the side, it doesn't work anymore.
For this feature (one voice), I would think everyone in the car should be able to control it. Even my voice activation button is the middle most button of the Ultrabay.
Let me know how that works though. I have the USB adapter, I just don't use it. Never saw that much difference. Plus the ALC883 noise/echo cancellation, I found, is much better. Can't say how I came to that conclusion, but it definitely is better.
Austria??? Oh man, I LOVE that place! Spent a lot of time in Villach. If there is heaven on earth, it's somewhere around there.
Edit: Just checked the map, you're just a hop,skip, and a jump from Klagenfurt/Villach. I so envy you! Villacher beer rules! Crawled home through the snow many a time.
