No, this is wrong. It's a condition: you *must* not use the Service in that way. The reason is that Google gets data from providers who do have turn-by-turn directions and who have specified that competing products/application may not be implemented. I don't see how clicking a "Refresh my position" button does not make it "real-time". If anything, it makes it *more* real-time! However, you *can* use the Service to show a route -- the query "How do get from A to B?" could be run at any time and doesn't provide real-time guidance. I did have the thought that that may mean that you could recalculate your start point every so often, and display the route on the map along with the first one or two of the text directions "Head southeast on Smith Street for 140 yds. Take the first left into John Street." When the user needs more, they could click a button which recalculates "A" and gets the route to B from the new start point, which is displayed in the same way. "Head east on John Street for 500 yds. Take the third right into Brown Road." Note: to do this, you will need a map which should show the whole route A-B, because you are not using the entire textual content; and you will need to specify sensor=true in your API call. I would also recommend that -- because of the necessary interaction -- you get the user to acknowledge that they will not use your app while travelling in a vehicle, rather like satnav devices put up a warning not to alter settings while the vehicle is moving. BUT: again this may be baulked by being "synchronized to the position of a user's sensor-enabled device." It looks like Google's suppliers' lawyers have got it sewn up. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
