I've had Garmin Express and Communicator installed and tried webupdate as well. I've resorted to using EasyGPS. I uninstalled Garmin Express to see if that would make a difference and it didn't. It's an extra step, and the Rino only shows the name of the cache in the notes. I've re-installed Garmin Express and when I run it, it says Garmin Express doesn't support this device, and to use webupdater. I tried all versions of webupdater, still no joy.
