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. 186
