I did manage to get it to work, though not in quite the same manner. I tried restarting my computer with the GPS plugged in and gStart automatically ran and gave me the option to "Plan a Trip" or "Install Maps." I selected the "Install Maps" option and the SE USA map came up and I was able to select the areas I wanted and send them to my GPS. So, my problem is ultimately solved.
As far as getting the map to show up in Mapsource; the view option for the toolbar is selected but only the zoom magnifying glasses, the "Select a Map Scale" and the "Select a Map Detail Setting" show up. From what I understand, I have to have two maps installed before the map drop down will show up. I'm not sure what I should be seeing with just one map installed. There is still nothing showing up in the map or mini map windows.
