A review of the 2008 Acura TSX sedan has been posted over at CNET. 'According to Acura's press materials, the navigation system understands 653 voice commands, no small undertaking to learn. But the vast majority of these are "add-on" commands that extend a much smaller set of main action words. Once this latter list is in the driver's arsenal, controlling the main interior functions of the TSX is pretty intuitive and responds to a few natural-language questions ("How far to the destination?") as well as its more restrictive set of specific commands ("driver temperature 72 degrees"). After a couple days of really making the effort to learn the system, we began to enjoy the feeling of ordering the car around rather than pressing buttons. Even the commands that take substantially longer to say than it would to reach out to the touch screen begin to make sense to use when in heavy traffic, at highway speeds, or other situations where the driver's eyes should remain on the road.'
