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 hospital 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 the 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, changing 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
