Assuming that you have cached a download of your local area (see my earlier post on this topic) and as long as you launch a trip within the range of a wireless connection (before setting off on your trip), Google Navigation will behave as usual:
- It will direct you to the exact location with voice commands.
- If you go off the track, it will revise the route and continue with voice connections.
- You cannot launch a new trip once you reach your destination. I must investigate whether you can setup trips ahead of time.
It is noteworthy that at all times, Google Maps knows where you are located on the map. At all times, you can see your location move to different streets as you drive around. How does it do this?
Is Google Maps, even when you are in offline mode, when you are out of the range of a wireless feed, still actually communicating with GPS satellites?
