Preface
Navigation
The navigation system displays and tracks the
vehicle's position and movement on a moving map
display. When a destination is input, the navigation
system quickly calculates a route and guides you
along the route with pictorial displays and voice
prompts.
Current vehicle position
The navigation system integrates the GPS (Global
Positioning Satellite) signals received and the map
information stored on the DVD ROM to display the
position and direction of the vehicle. The system
also includes a gyroscope and a speed sensor that
enable it to display the present position even in
locations where the GPS signals may be blocked.
Memory point mark
Map matching
Since GPS navigation has an error of 100 – 655 feet
(30 m – 200 m), the position of your vehicle may be
displayed off the road. Map matching automatically
corrects this error so that the position of your vehicle
is displayed on the road.
Road preference setting
You can set your preferred road on the route to the
destination for up to 2 places if your local knowledge
helps.
Memory points
Locations you go to frequently
can be stored into memory and
marked on the map. The
system can store up to 200
points, excluding your home.
You can add icons at the
memory points so that the
system also displays the
icons on the map.

Motorway-preference selection
When searching for routes with the navigation
system, you can switch between searching for
routes that give priority to motorways and those that
give priority to ordinary roads. When you specify
motorway preference, the navigation system
automatically searches for a route that gives priority
to motorways and guides you along that route.
