NAVIGATION - GUIDANCE
The satellite navigation system guides the driver to the destination
that he has set in accordance with a chosen route.
Initially, it searches for the destination required by the user, then
it calculates the route and  nally it provides the visual and vocal
guidance instructions.
A point of interest (POI) is represented by an icon on
the map, it represents an airport, a station, a town
hall, ...
WHAT IS A POINT OF INTEREST (POI)?
Up to 40 different icons may be displayed (refer to the
section "Points of interest icon").
They are classi ed in 5 groups and identi ed by one
colour for each group:
- Shops,  nance and businesses (Green),
- Vehicles and travel (Dark blue),
- Restaurants (Orange),
- Public places and emergency services (Brown),
- Entertainment and attractions (Blue).
GPS (Global Positioning System) consists of several
satellites arranged around the earth. They continuously
transmit digital signals which travel at the speed of
light, on 2 different frequencies.
At any given time, the system receives its position
in relation to the satellites detected and the time of
transmission of the signal.
This enables the telematic unit to calculate its position
and therefore that of the vehicle.
A repositioning process using the map database stored
on the hard disk allows the vehicle to be positioned
on the road network, so improving the accuracy of the
vehicle location function.
GPS SYSTEM
WHAT IS THE NAVIGATION SYSTEM AND GPS?
The system's measurements may be inaccurate if the vehicle is:
- in a tunnel or underground car park,
- underneath a two-level motorway,
- in an area with several very high buildings,
- surrounded by closely planted trees.
Depending on the vehicle's situation and the reception of the GPS
information, the displayed information may disappear from the
screen temporarily.
WHAT PRECAUTIONS SHOULD BE OBSERVED IN
ORDER TO MAKE BEST USE OF THE SYSTEM?
Do not place anything on or near the GPS aerial.
Do not use any digital communication equipment (personal
computers, etc.) near the GPS aerial.
Do not af x any re ective  lms or  lms containing carbon to the
windows.
