I have my GPS plugged into my laptop,and they match up no problem. I have the option of National Geographic Topo,Mapsourse or DeLorme Topo loaded on the C drive.Everything is cool. National Geographic or DeLorme will track no problem. I have a downloaded Pocket Query downloaded to each software,things still good. I can see the caches on all (3) programs.Now because I am off line what hoop do I need to jump thru to be able to view the cache description .I have both a Colorado and a 550 and they can show me a description and 5 logs no problem.The answer has to be right under my nose.
