Maps

This section includes basic information that you need to
know about the map database.
The maps are stored on a DVD-ROM. The 48
contiguous Unites States and portions of Canada are
contained on one disc. The U.S. map database includes
interstate freeways, state highways, country roads
and major and general streets.
Refer to the "Navigation System Map Disc" manual to
view the explanation of map coverage. The map
disc manual will be in your map DVD case when the
vehicle is delivered from the factory.
When your vehicle is delivered from the factory, the
dealer may have installed the map DVD. If the DVD was
not installed in your vehicle when first purchased, do
the following:
1. Turn the ignition switch to RUN or ACCESSORY.
2. If already loaded, eject the map DVD or audio
CD from the slot.
3. Load the map DVD into the slot by inserting it
partway. The system will pull it in.
Once the DVD is inserted correctly, you will have the
following two choices:
•
ENG (English)
•
FR (French)
You can select the language at this time. See "Language"
under Screen Setup on page 1-4 for information on
choosing a language. Once a language has been
selected, select NEXT to plan a route. The map will
appear showing your current vehicle position.

Map Adjustments

The system allows you to adjust the scale of view on
the map. Also, the map will scroll automatically based on
the direction you are traveling.
To view a larger or smaller scale of the map, press the
zoom in or zoom out keys. See "Hard Keys" under
Using the Navigation System on page 2-2 for more
information.

Map Scales

The scale of a map can range from 1/32 of a mile
(0.05 km) to 128 miles (206 km).
