Maps
This section includes basic information needed to know
about the map database.
The maps are stored on a DVD. The 48 contiguous
United States and portions of Canada are contained
on one disc.
Detailed Areas
Road network attributes are contained in the map
database for detailed areas. Attributes include
information such as street names, street address, turn
restrictions, etc. A detailed area will include all major
highways, service roads, and residential roads.
The detailed areas include points of interest (POI) such
as: restaurants, airports, banks, hospitals, police
stations, gas stations, tourist attractions, historical
monuments, etc. The map database may not include
data for newly constructed areas or map database
corrections that are completed after the production of
the disc. The navigation system will provide full
route guidance in the detailed map areas.

Limited Guidance Areas
Any area that is not classified as detailed is a limited
guidance area. Limited guidance streets will be
displayed on the map display but route guidance
may not be given on these streets. Some POI
categories, such as the city center POI category, and
some street addresses are included in the limited
guidance areas.
The navigation system will inform you by voice prompts
when you are traveling into a limited guidance area
where route guidance will not be available. The street
maps and the directional arrow displayed on the
navigation system can then be used to determine the
remaining route to your destination.
