I have a Garmin eTrex HC and have saved some really useful coordinates and other things from expeditions in remote West Papua in the region of Puncak Jaya/Carstensz Pyramid
I have no idea how to get the data and maps into any format into my Macintosh, nor do I understand how then to prepare this so it can be displayed or shared with others on one of my mountains pages?
Really need some help understanding ...
