U (Space): Select to enter a space between characters or the words of a name. Backspace: Select if an incorrect character has been entered. To make name entries easier, the system only highlights the characters that can follow the last one entered. For example, if a Z is entered, a T may not be available for selection. 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 includes 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 provides full route guidance in the detailed map areas. If a name does not display after entry, it may need to be entered differently or the map DVD disc may not contain that information. See Database Coverage Explanations on page 5‑59 for more information. Maps This section includes basic information that you need to know about the map database. The maps are stored on a DVD. The United States, Canada, and Puerto Rico are contained on one disc. Limited Guidance Areas 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. 5-14
