This one is a C330 StreetPilot. It can use a 4 gig SDSC type card, but those have been real hard to find since 2006, after the SDHC standard was released. With OSM converted data only around 1/3 of the USA can be squeezed onto a 2 gig SD. Has anyone made a complete USA (at least the 48 States) map from OSM, stripped to the bare essentials of just roads and address data for navigation, and have it fit onto a 2gig SD? Could leave out all the lakes, rivers, railroads etc.
