No more stopping for directions. With detailed street maps of North America and a hefty points of interest database at your fingertips, you have all the data you need to navigate North America. Garmin offers full coverage of City Navigator North America NT on both DVD and preprogrammed cards, making it easy and convenient to load maps to your NT compatible Garmin. Just plug our preprogrammed cards - available on both SD or micro SD data cards - into your GPS and go. Our City Navigator North America NT DVD and data cards include the same detailed maps, points of interest and coverage areas as our traditional City Navigator North America data, just compressed differently for your NT compatible unit. It also includes traffic data that allows certain units to use traffic receivers. This product is for NT compatible units only.
