So I was up in the mountains a couple weeks ago (Arnold/Murphy/Big Trees area) and had absolutely zero phone reception. No biggie, that's expected up there. the droid's gps was still tracking me, but it ran out map to show me where I was, and couldn't load any more. After a little searching and no luck, I'm trying to find a way to download maps to the phone so that I can still use navigation with the pre-loaded maps if I get GPS reception. That way you wouldn't have to rely on being near a 1x or 3G connection. Anyone else try this or hear of it being (or not being) possible?
