Does iPad gps work without 3G coverage, particularly with a nav app.
I'm traveling to an area that does not have ATT coverage. I was hoping to download a navigation app like Navigon which stores the map data on the device and uses the gps chip to plot location. I'm getting very conflicting feedback regarding the functionality of the gps chip when it loses an assist from the 3G carrier, as well as speculation that the app doesn't store the maps on the device - potentially giving me a location (coordinates) without the visual overlay of the map itself. This question has been posed all over the place and there is no definitive answer. Does the gps chip function without 3g as well as a portable gps? And does the device store the map or rely on the 3G data feed to refresh the display?
