Although my first reply from Garmin could have been written on toilet paper, it was so useless, they did confirm that all versions that include a GPS are elligible for you to pay them more money.
I asked again how I might line their pockets so we will see what happens.

"Thank you for contacting Garmin International. You cannot update the software version of the program, a new map version is available every year but the software must be re-purchased. A lifetime map update can not be purchased for the software only version as well. If purchasing the Mobile 10x version, bundled with software, then a map update is possible, as well as adding the Lifetime maps to the device."
