> Third, it can't navigate a path without connecting to the satellite
How else would it work? Just sense which way the wheels are pointing and track the speedometer?

It should use the last known location and vector to find a route. It doesn't. My guess is that it loses the satellite, sees it again and starts recalculating, loses it, and repeats this cycle. Unless the satellite is visible for a long enough period, it never produces any path. Even an out-of-date path would be more useful than simply nothing.

Edit: Ah, I see, I meant something sort of other than that read. I've certainly had the experience of not being able to download maps, but mostly on hikes in the middle of nowhere. When I use navigation on foot in the city, hadn't had the problems I have with in-car nav.
