"As far as using your Nuvi goes, you can upload caches directly to your Nuvi by connecting it to your PC with the USB cable and clicking the 'Send to USB' button. It will detect your Nuvi, and any installed SD Card, and give you the option to send to either. The geocache/s will then show up in your Favorites (Menu -> Where To -> My Locations -> Favorites) with the GCxxxxxx code.
Cool thing, say you load three caches. Choose the furthest away cache as a 'Go to' destination. Then go back into the Where To menu and choose the other geocaches in the order of closest to next furthest. You will be given the opportunity to add them as 'Via' waypoints. Your Nuvi will then street navigate you to each, in order. Not sure how it will handle caches if you put them in different orders. "
There is not Send to USB button - only LOC, GPX, Send to GPS, and Send to Phone buttons.
Please clarify for Nuvi.
