Database Coverage
Explanations
Coverage areas vary with respect to
the level of map detail available for
any given area. Some areas feature
greater levels of detail than others.
If this happens, it does not mean
there is a problem with the system.
As the map data is updated, more
detail can become available for
areas that previously had limited
detail. See
