If you're using only the factory-loaded background map, the maximum
zoom range for showing additional map detail is 20 miles. You can con-
tinue to zoom in closer, but the map will simply be enlarged without
revealing more map content (except for a few major city streets.) Load
your own high-detail custom map made with MapCreate (or a pre-made
FreedomMap from LEI), and you can zoom in to 0.02 miles with mas-
sive amounts of accurate map detail.
Map Pages with high-detail MapCreate map of an urban area loaded on
the MMC. Arterial streets appear at the 4-mile zoom range (left) with a
few Point of Interest icons visible. Numerous dots representing Points of
Interest are visible at the 2-mile range (center) along with minor streets.
At a 0.4-mile zoom (right), you can see an interstate highway with an
exit, major and minor streets as well as Point of Interest icons.
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)
and some major city streets. Also included are Interstate, U.S. and
state highways, large- and medium-sized lakes and streams and more
than 60,000 navigation aids with 10,000 wrecks and obstructions in
U.S. coastal and Great Lakes waters. New for 2007 are more than
3,000 enhanced lake maps that show better defined shorelines, depth
contours and other underwater features.
MapCreate custom maps include massive amounts of information not
found in the background map. MapCreate contains: the searchable
Points of Interest database, all the minor roads and streets, all the
landmark features (such as summits, schools, radio towers, etc.); more
rivers, streams, smaller lakes and ponds and their names.
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
