We're having the same problem with the Garmin 600. The caches not showing don't seem to have anything in common, or not in common with the ones that show. Tried the filter settings suggestion.
Tried putting the ones that don't show in individually (in a list of their own) and they still don't show.
edit: we fixed the problem by altering a setting slider on the sat nav to include all terrains.
