GENERAL
INFORMATION
The navigator integrated in the
CONNECT Nav+ allows you to reach
the chosen destination by visual and
voice instructions. Use of the naviga-
tion system is quick, convenient, safe
and above all very flexible because it al-
lows you to call up already pro-
grammed destinations or points of ref-
erence such as hotels, monuments,
public structures, fuel stations or Fi-
at Dealerships.
The vehicle position is determined
through the GPS system (Global Posi-
tioning System) installed on the vehicle.
The GPS system is fitted with an an-
tenna and a reception module inte-
grated in the telematic system. This sys-
tem configuration dynamically process-
es the satellite signals, those from the
right and left odometer, the reversing
signal and the information of the gyro-
scope integrated in the navigation com-
puter, integrating them with the cur-
rent position of the vehicle to obtain an
“estimated vehicle point”.The signals from the right and left
odometer make it possible to deter-
mine the movement of the vehicle, the
gyroscope signal identifies any turn-
ing and the reversing sensor distin-
guishes the direction of travel.
The Fiat navigation system helps the
driver while he/ahe drives by suggest-
ing vocally and graphically the opti-
mum routing to reach the preset des-
tination.IMPORTANT NOTES
– GPS reception is difficult under
trees, among tall buildings, in multi-lev-
el car parks, tunnels and everywhere
reception of the satellite antenna may
be hindered.
– The GPS system needs about 15
minutes for activation if the vehicle
battery is disconnected.
– The GPS system needs a few min-
utes to determine the new position of
the vehicle if it is turned off and the ve-
hicle is moved with the system off (e.g.:
by breakdown van).
– In the lack of satellite information,
the system uses information from the
gyroscope and from the special sen-
sors for temporary data analysis.
– The GPS satellite aerial must not
be covered with metal or damp ob-
jects.

The navigation system sug-
gestions do not exempt the
driver from full responsibility due to
his driving behaviour and to com-
pliance with road and other traffic
regulations. The responsibility for
road safety always and in any case
lies with the vehicle driver.
WARNING

The instantaneous vehicle position is
identified in the CD-ROM and shown
on the display together with the topo-
graphic characteristics of the area
memorised on the CD-ROM. Access
to data on the CD-ROM requires a
few moments waiting for the map dis-
plays.
The system constantly compares da-
ta from the speed sensor, from the re-
verse gear sensor, from the GPS an-
tenna and the gyroscope to automat-
ically compensate changes in temper-
ature, pressure or any other occur-
rence that may lead to a false position
detection in any way.
IMPORTANT NOTES
– Accurate self-adjustment of the
navigation system requires approx.
1-10 km of travel the first time and
when tyres are changed.– Continuous lack of grip at the
wheels (for example skidding on ice),
makes the system temporarily detect
an incorrect position.
The navigation system is completely
managed by the telematic system,
therefore the only operations that may
be required are replacement of the
CD-ROM to set the map of another
area or an updated map.
Access to the navigation main func-
tions is gained by short push on
“NAV” key 20-fig. 1after turning on. Long push on “NAV” key 20-fig. 1
engages the navigation system Mute
function, which will therefore no
longer provide voice instructions.
When the Mute function is on, the dis-
play shows “Nav Mute”. To turn the
Mute function off press again the
“NAV” key 20-fig. 1at length.
Each time you start the engine and
select the navigation function, the dis-
play will show a page with the cautions
for using the system fig. 47. To con-
tinue system use this page must be
confirmed pressing the “NAV” key
20-fig. 1. This page will not be dis-
played as long as the system is on.
