I'm considering using the Google Navigation GPS on my Motorola Droid for a long distance trip to Canada. The trip is about about 900 Miles from Washington DC to a somewhat remote part of Canada. I've used the Google Navigation for many trips around the Washington DC Area and never had any problems, but it was always within range of 3G coverage. The Main Questions are: Will the Google Navigation GPS continue to work fine when passing though area's with no 3G or even no cell phone coverage at all? Like can it work just based on the GPS Satellite signal like a regular GPS? It seems if it can only operate when in range of 3G or cell signal or both, that it will not work as a GPS for a long distance trip where I will travel though area's that I know do not have 3G coverage and likely not cell phone coverage either.
