Android in GPS technology and devices Posted June 1, 2012 With some of the other map programs you can download maps from many sources at no cost. You pick the area you wish to hunt and depending on your memory card size you can download detailed maps of any area. It suprised me that this was not available with the Geocaching Android program. I was hoping I was wrong. Before I use the other Map program I go to a WIFI spot and download the maps and it is free. Thanks for the reply My guess is that map downloads are in the same realm as music and video downloads, which most likely means you need a data plan, or be ready to pay hefty data download charges each time you use the app in the field.
