Navigation Introduction and operation of
the navigation system Introduction General information
The current position of the vehicle is deter-
mined through the GPS satellite system
(Global Positioning System). Sensors in the
vehicle measure distances driven. With the
detailed material stored in the map, and ac-
cording to the traffic news stored, all the val-
ues obtained are compared. Similarly, the
traffic reports are taken into account to calcu-
late the route (dynamic navigation
››› page 35 ). With all the data available, the
n av
igation system calculates the optimum
route to the destination.
The destination is defined by entering an ad-
dress or a point of interest, e.g. a petrol sta-
tion or hotel.
Spoken instructions and visual guidance on
the navigation unit and the combi-instrument
direct you to your destination.
Depending on the country, some infotain-
ment system functions can no longer be se-
lected when the vehicle is travelling above a
certain speed. This is not an operational er- ror; it is to comply with the legal require-
ments.
Limitations during navigation Possible errors during navigation
When the navigation system cannot receive
data from the GPS satellites (dense tree foli-
age, underground parking areas), it is possi-
ble to proceed with navigation using the sys-
tem of vehicle sensors.
For the navigator to work properly, navigation
should begin when the signal is received
from the satellite.
In areas that are not or only partially digitised
on the data medium (e.g. insufficient defini-
tion of one-way streets and road categories),
the navigation system will still attempt to
provide route guidance.
If navigation data are unavailable or incom-
plete, the navigation system may be unable
to determine the exact vehicle position. As a
result, the navigation may not be as exact as
usual.
Area of navigation and validity of the
navigation data
Roads and streets are subject to constant
change (e.g. new roads, changes to street
names and house numbers). After some
time, navigation data will no longer be up-to-date. This may lead to inaccurate or incorrect
route guidance.
Current navigation data media and versions
for other countries are available from SEAT
dealerships.
Note
The user must pay attention to the road
signs, which take precedence over those
shown on the screen. Use navigation data from a memory
card
Memory cards containing updated navigation
data can be obtained from SEAT dealerships.
●
Insert the memory card ›››
page 23 .
● Do not remove the memory card while test-
ing. Wait for the testing icon to disappear.
If the inserted memory card contains valid
navigation data, the following message ap-
pears: “The source contains a valid naviga-
tion database”. It is now possible to navigate
with the memory card data. When the memo-
ry card is no longer needed by the hardware,
it will be prepared for removal ›››
