GPS

What is the navigation system and
the GPS?
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 fi nally it provides the visual
and audible guidance instructions.
The GPS (Global Positioning
System) consists of several
satellites distributed 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 cal-
culate its position and therefore that of
the vehicle.
A repositioning process using the map
11
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.
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 affi x any refl ective fi lms or fi lms
containing carbon to the windows.
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 is a point of interest (POI)?
A point of interest (POI) is
represented by an icon on
the map, it represents an
airport, a station, a town
hall, ...
Up to 40 different icons may
be displayed (refer to the
section "Points of interest
icon").
They are classifi ed in 5 groups and
identifi ed by one colour for each group:
- Shops, fi nance and
(Green),
- Vehicles and travel (Dark blue),
- Restaurants (Orange),
- Public places and emergency services
(Brown),
