I have to say that it looks promising. The car-kit has it’s own GPS chip, so it will be more accurate and faster than what it would be using the A-GPS chip found on the iPhone. Basically, the iPhone only works as the processing unit and a screen for the whole navigator. I think that if I’d be in need of a “true” navigator now, I would go with this.
