I didn't get the impression that the demo view was for in-store display. It's positioned in the menu prominently enough to be considered a test-run of the route to see how it plays out. And I don't mind the fact that it loops, but there should be a much clearer way to stop it looping and get to properly navigating.

I will say that the iPhone version of TomTom is much improved over the stand-alone version I borrowed from a friend back in June. That model might have been a few years old though.
