Oh sure, put this meandering in the wilderness off on me!
To bring this thread back on track, I just procured a slightly used Garmin Street Pilot 2720 and was able to register it in my name. Garmin provided a free one time map upgrade when I did that. Try to register your Garmin if you can, the previous owner has to unregister, but if you can you may be able to get the latest maps.
