Only the area maps can be saved to the data cards from the Mapsource CDs when using the USB data programmer. The area maps are the main regional maps for a large specific area. For example, Melbourne, Florida is include in the Orlando area map. Waypoints and routes cannot be saved to the data card via the USB programmer. Waypoints and routes created or used in the Mapsource software can only be transferred to the GPSMAP 295 via the serial port / PC cable connection between the computer and GPS.
