Hey Antler Eater, You download the Webupdater on the garmin webpage. After you get that installed and you have your disc that came with the GPS installed on your PC thenyou can connect your GPS to your PC and launch the webupdater and it will search for your GPS and after it does it will show you the available software and firmware updates from Garmin. Just select and it loads it all with no issues. It really helps with the new updates. I normally launch the Webupdater on mine about once a month.
