Limited Guidance Areas :
These areas exist in the United States map database only. Any area that is not included in the detailed
area list is a limited guidance area. These areas include the road maps but may not contain complete road
network attribute information. Road network attributes include information such as street names, street
address, turn restrictions, etc. Complete road network attribute information is needed to provide full
route guidance. Due to the incomplete road network attributes, route guidance is available only on some
of the major roads in the limited guidance areas. The surrounding streets will be displayed on the map
display but route guidance may not be given on these streets. The navigation system will inform you
when you are travelling into a limited guidance area where route guidance will not be available. The
street maps displayed on the navigation system can then be used to determine the remaining route to your
destination.
Non-detailed Areas :
These areas exist in the Canadian map database only. Any area that is not included in the detailed area list
is a non-detailed area. Some of the major roads are available in the non-detailed areas and may be
selected through the intersection and the freeway entrance/exit route planning options. The city center
category is available in the all point of interest planning option. Residential roads, service roads, points
of interest (except city center) and street addresses are not included in the non-detailed map areas.
