Ordering Map DVDs

information available when your vehicle was purchased.
The map DVD is updated periodically, provided that
the map information has changed. To order a new map
DVD, contact your dealer.
Database Coverage Explanations
Coverage areas vary with respect to the level of map
detail available for any given area. Some areas will
feature greater levels of detail than others. If this
happens, it does not mean there is a problem with the
system. As the map DVD is updated, more detail
may become available for areas which previously had
limited detail. See Ordering Map DVDs on page 2-35.
