Background map vs. MapCreate map content

The background map includes: low-detail maps of the whole world (con- taining cities, major lakes, major rivers, political boundaries); and me- dium-detail maps of the United States.

The medium-detail U.S. maps contain: all incorporated cities; shaded metropolitan areas; county boundaries; shaded public lands (such as national forests and parks); some major city streets; Interstate, U.S. and state highways; Interstate highway exits and exit services informa- tion; large- and medium-sized lakes and streams; and more than 60,000 navigation aids and 10,000 wrecks and obstructions in U.S. coastal and Great Lakes waters

MapCreate custom maps include massive amounts of information not found in the background map. MapCreate maps contain the searchable Points of Interest database, all the minor roads and streets, all the landmark features (summits, schools, radio towers, etc.) and smaller lakes, rivers, streams, and ponds.

What's more important is the large scale map detail that allows your GPS unit to show a higher level of position accuracy. For example, the background map would show you the general outline and approximate shape of a coastline or body of water, but the higher detail in MapCre- ate shows the shoreline completely and accurately. Many smaller is- lands would not be included in the background map, but are in Map- Create.
