Just wondering if any of you have tried this one out?

I read this thread and did not see it mentioned. It looks like it is exactly what we would need and looks much cleaner than the Blackberry Music Gateway and the Belkin unit.
My only concern is audio quality.
On the site it says that it auto pairs when the car is powered on. I think I may try out this one if no one else has any feedback.
