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 is 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.

ate map.
