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.
East
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.
