It is very easy to download caches from the map and save them as GPX-file for later offline use. Here is an example workflow how to do this.
2) The center of the map should point to your target position. Press the refresh button to load the caches around this point.
You should have been authorized to geocaching.com before, otherwise view the appropriate HowTo Login to geocaching.com.
After some seconds the caches according to your filter-criteria are displayed on the map. The filter criteria can be accessed by the Filter-button of the menu.
4) The download page appears
Type in a descriptive name for your download and press the back button once to leave the input box.
The checkbox “Download full descriptions” should be selected to download the description text and logs of each cache.
5) Press the Download-button to start the download progress.
Ensure a stable WLAN-connection and connect your phone to a power supply while long download sessions.
After 1-2 minutes the caches should have been downloaded.
Now you have one more GPX-file in your Waypoints-file-collection.
Thats all you have to do to download caches from the map as a new GPX-file for later offline use.
Now take a look into your Waypoints-collection.
