Information Features
Unit Conversion
To perform a conversion:
1. Enter a numeric value to be converted (for example, 100).
2. Select the type of unit you want to convert (for exampl e, weight). The screen for that conversion type appears (see illustration in step 3).
3. Select the base unit (e.g., pounds) that you wish to convert to some other unit. All other units will change automatically depending on the base unit value. In the example below, 100 lbs converts to 1600 ounces, 0.05 ton (U.S.), etc.
NOTE: If you do not enter a value to be converted, only “Temperature” units are selectable. Conversions using negative value may produce meaningless or physically impossible values.

Database Limitations
You will find that some points of interest (POI) may be missing when you search the database. This can be caused if at the time the database was gathered, the name was misspelled, the place was improperly categorized, or the POI change is not yet in the database. This means you may not find places listed that you know exist. This is also true for police agencies and hospitals. In outlying areas, facilities listed may not be the closest. Always check with local information sources if you need law enforcement or ho spital services.
Every effort has been made to verify that the system’s database was accurate at the time it was created. However, businesses do close or relocate, and new businesses start in th e old locations. For this reason, you may occasionally find inaccurate information when you select and drive to a point of interest (for example, a restaurant is now a jewelry store). The number of these inaccuracies increases the longer you go without an update.
The digitized map database reflects conditions as they existed at various points in time before production. Accordingly, your DVD may contain inaccurate or incomplete data or information due to the passage of time, road construction, ch anging conditions, or other causes.
Due to ongoing software and database improvements, navigation disc versions may change in the middle of a production year. The version shipped with your vehicle was the most recent available at the time of production and is considered standard equipment for that vehicle. There is no free program to retrofit early production vehicles with the latest disc. For DVD ordering information, see page 105.
In addition, this database does not include, analyze, proc ess, consider, or reflect any of the following categories of information:
• Neighborhood quality or safety
• Population density
• Availability or proximity of law enforcement
• Emergency, rescue, medical, or other assistance
• Construction work, zones, or hazards
• Road and lane closures
• Legal restrictions (such as vehicular type, weight, load, height, and speed restrictions)
• Road slope or grade
• Bridge height, width, weight, or other limits
• Road traffic, safety, or conditions
• Weather conditions
• Special events
• Pavement characteristics or conditions
