Very well done

The GPS integration is genius. The automated tour guide comments on upcoming sites, turns that you have to make, etc. perfectly. The historical content thrown in with the narration is also excellent. When you compare this to what a guided tour would cost – where you dont have any flexibility to stop for an hour and do something else when you want - this is a steal. A slight quibble is that if you get off course it really wont bring you back. It just remains silent until you have returned to its route. But this is minor.
