My 14xx garmin only has 2 gigs of memory. Im stuck using maps over 1 year old since I refuse to use a micro sd card.

The question is this - is there any way to upgrade my older where-to-go search-places like atms, restaurants, museum, etc from a new mapset, or is this information hardcoded into each mapset so that to upgrade this I have to upgrade the whole map? There isn't some small file I can just grab off a new mapset and stick it with my older mapset?
