I checked for Garmin/GarminDevice.xml and it is there. I used webupdater to re-install updates to the unit and proceeded to load Garmin Base Camp because it has all of my saved routes. When it loaded, it gave me an error message stating that it couldn't work with the "current.gpx" file. I loaded my routes back to the GPS and I'm now re-loading the most recent map update. It's taking forever-and-a-day to install. It currently is transferring at a rate of 771.2 KB/s.
