Not sure what the issue is, but I cannot load a cache to my Garmin 450 Oregon. When I select "write to my GPS" I get a popup that says: "Either the GPS does not support the items or Garmin Communicator Plugin needs to be updated." The communicator is already updated, but to be sure, I switched PC's, reinstalled the various software for the device so it would work on the PC, updated the communicator plug in, and even tried using Chrome instead of Explorer, and still -- I keep getting this message. Yikes! It is a beautiful day and we'd love to geocache ... Any ideas?
