Hi all. Just got my first GPS unit for porospecting in S.E. Alaska, Rhino 530. Reading the manual doesn't pull things together, especially a simple description of what mapsource, homebase, geocoaches, mapquest and PIO downloads are? Is there a source of beginner basics that explain these concerning what does what and/or is used for?
Whew, got a headache just getting around the garmin site and finding a forum link.Thanks for any help, Thomas
