The StreetPilot is a family of Global Positioning System (GPS) devices manufactured by Garmin for use while driving. Many Garmin StreetPilot users update the device with new maps. The StreetPilot has a limited memory capacity that varies per StreetPilot model. Once the memory fills to capacity, you must delete maps from the device to make room for new maps. Eliminating unused maps will also make room for media files.
