Yes and no. If I enter a zip code (because that is the town I'm visiting in)I see local caches, but my phone says it's as many miles away as we already are. And using the 'navigate to' my phone wants me to 'travel' from home zip code. Not the few miles, or feet I may be actually standing away from a cache in the visiting zip code.
And also, when I have searched the laptop for the GC codes and enter them while out in the field I get a message of no such cache.
