We have to clarify some things.Thanks for all the info...I'm pretty much a GPS virgin so...how I understand it is I can install a memory card and it will remember the route I took and keep it in memory...? Do you know if the 550 has better mapping for they're base map or are you saying most if not all the base maps are basically the same unless you purchase the (City Navigator NA NT series) which it seems as though you may not think is worth it for back road adventures...? Thanks for your help. I'm also trying to decide on which GPS too purchase before our trip to TN and NC. The 550 is pretty damn pricey for sure...
The only units that have 'base maps' in them are units that do not come preloaded with full mapping of North America - the base maps provide 'fill' for those places you don't have in your memory card. The 276, the Quest and the older 2600 series, Streetpilot and so on are examples of this type of unit.
Nuvi and Zumo have full mapping on board, so there's no base map, because there's no need for a base map. And those maps are the same maps that you download into the memory chips in the 276 or to the memory of a Quest and so on . . . so in the end, the downloaded maps provide detail, routing information and have Points Of Interest (POIs) that are sent to the downloadable device.
Just to complicate things, Garmin does offer some units with full mapping of the US AND Europe on board - and you thought Zumo cost a lot of money!!
All Garmin CNNA maps from the present year are the same, have the same POI data and will route the same as a consequence.
