In the first example below, the range is 4,000 miles from the left edge of
the map to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its
coverage area and the amount of mapping detail shown. There are 37
available map zoom ranges, from 0.05 miles to 4,000 miles.
Map Page opening screen (left). Zoomed to 100 miles (center) and
zoomed to 15 miles (right). Over Zoomed means you have reached the
detail limits in an area covered only by the basic background map.
Zooming in any closer will reveal no more map details because a high-
detail custom map has not been loaded on the MMC.
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, and you can
zoom in to 0.05 miles with massive 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 6-mile zoom range with a few
Point of Interest icons visible (left). Numerous dots representing Points
of Interest become visible at the 3-mile range, along with minor streets
(center). At the 0.6-mile zoom, you can see an interstate highway with an
exit, major and minor streets as well as Point of Interest icons (right).
