Any area that is not classified as detailed, is a limited guidance area. Limited guidance streets are displayed on the map 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 informs through voice prompts when you are traveling into a limited guidance area where route guidance is not 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.
