Perhaps the mapping programs have improved over the years.
I have a StreetPilot 2820 and apparently you have to hack a map DVD and create a smaller unlocked map to be able to update the map on it using MapSource. The online updater recognized the unit, but won't update it. I found a guy on FleaBay that provides the upgrade service. I also have a Nuvi 855 that I will have to retry.
