We are looking for a Garmin GPS for hiking. Bare with me because I'm a newbie and are not familiar with the wording I'm looking for but I think it is 'Waypoints' or 'Geocaching'. We would like it to be able to mark our camping site and go off hiking and make it back to camp with no problems. Would also be nice to have coordinates in case of an emergency. These are our main request above but since we would be purchasing a GPS it would be nice to have road site assistance as will.... Be able to put in an address/city for directions.....Free map and traffic updates a plus. We like to purchase our products like this at Costco because of the return policy so I would like to know if one of these product would give us the feature we are looking for.
