Google maps works by transferring data asynchronously from Google's various data servers to a user's computer, pulling in map tiles and all sorts of other information on demand. So if there's no internet connection, there's no way to communicate with Google's servers. So, no offline usage.
It doesn't matter if you've cached some resources (and you're not supposed to anyhow). As others noted, Google Earth can display things offline. If you just want a non-live image of a route, then you can try using the Static Maps API to generate an image of the route, which you can save and view anywhere (as long as you keep the google branding on the image) -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
