I have a basic GPS unit (Garmin eTrex H) and it works just fine, but it's a real pain to print out each cache in hardcopy form (for clues, comments, cache info, etc.), put in the GPS coordinates manually into the eTrex H, then use Mapquest or Google to figure out how to drive to the approximate location of the geocache.
Is there a faster, easier way to geocache? Seems like paperless caching is the way to go, but I have a question (assuming I'm using something like the eTrex 20): After transferring the cache into the GPS unit and indicating that I am now searching for that cache, will it give turn by turn DRIVING directions, assuming I'm more than a few hundred feet away from the cache? If so, do I need to buy additional maps and load it into the GPS unit?
Basically, I'm looking to be able to go to geocaching.com, enter in a location I'll be visiting, load into my GPS unit however many caches that are in that general area that I choose, choose one of the geocaches I'd like to search for, then my GPS unit will tell me how to get there, including driving directions. Then once I'm there, the GPS unit will tell me how to get there on foot and give me access to the comments and hints as needed.
Assuming I can have this, what are my GPS unit options?
