Stumpled upon this question and I hava a follow-up:
yes, I DO need to input and search for GPS locations - in Multistage Caches, where every stage is only in the text instead of appropriate waymarks, which btw wouldnt be shown (and thus not navigable) anyway (the waymarks I mean).
I use googlemaps for that so far, but i wish i could input 1 to x waypoints in the tool myself, where it navigates me to, just like a "normal" gps would do. Or did I just didn't find that feature? Then I appreciate any help...
