INTRODUCTION
Functions
The navigation system
uses signals from Global
Positioning System (GPS)
satellites together with
information from vehicle sensors
and map data stored on IRIS to
determine the precise location of
the vehicle.
Using this data, the system is
able to create the optimum route
to your destination, taking into
account any journey preferences
you may have set, i.e. quickest
or shortest route.
To set your preferences, see
Options, page 89.
Creation of a specific route is
achieved by using the on screen
menus and the IRIS controls, to
make your selections.
This results in your route being
highlighted on the map in
orange. Once you have started a
journey, turn information is
displayed on the IRIS screen,
supplemented by voice guidance
if required, at appropriate points
during the journey.
