I take it you were referring to loading the geocaches, not the pictures. I have tried this now, I set up a folder labelled 'Garmin, GPX'on the sd card, pasted the geocaches into it and deleted them from the internal memory, checked the GPS, and it works.
However when I download the GSAK database into the Monterra again, it puts the caches into the Garmin folder on the internal memory again, whereas I would like to download them onto the SD card, thus updating/overwriting the existing file.
I was wondering if I deleted the 'Garmin and/or the GPX' file on internal memory, whether the GSAK database would then load to the SD card instead of the internal memory, but I don't like to take the risk, without confirmation that this will work.
Can you help me please?
