I perhaps should have said find rather than navigate. I don't expect turn-by-turn navigation when it has no way of knowing where I am. I'm not talking about it directing me along a path; but about finding the path in the first place.
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 Even an out-of-date path would be more useful than simply nothing.
