Buyer beware! The 610 is a significant improvement over the older 600; it has a number of great features, but... When you download unknown (puzzle) caches onto the GPS, don't expect to be able to edit the coordinates with new numbers derived by solving a puzzle. It can't be done, even though Magellan incorporated the requisite programming into its waypoints section to edit coordinates of those. The Magellan call center, outsourced to the Philippines, could not understand the problem (three times) except to say "why not just enter the geocache as a waypoint?" Why they would include the capability for one aspect of their GPSrs (waypoints) but not another (geocaches) is baffling.
