The Garmin StreetPilot C330 GPS device comes preloaded with maps of North America. As time goes on, cities and towns change and expand and new places are founded, creating the need for new maps. To provide the most accurate directions, Garmin provides updated maps that reflect these changes to its customers. The updated maps can be downloaded from the Garmin website and transferred to a Garmin GPS device using the company's proprietary software.
