Introduction
General information
The current vehicle position is determined by means of the GPS system
(Global Positioning System). Sensors in the vehicle measure distances driv-
en. The measurement values are adapted using the detailed information
from the navigation data medium maps and according to the stored traffic
management. Where applicable, the TMC traffic reports are included in the
route calculation ⇒ page 72. The navigation system uses these data to
determine an optimal route to the destination.
The destination is defined by entering an address or a point of interest, e.g.
a petrol station or hotel.
Navigation announcements and visual guidance on the navigation unit and
the instrument panel direct you to your destination ⇒ page 65.
Depending on the country, some radio-navigation system functions can no
longer be selected when the vehicle is travelling above a certain speed. This
is not a malfunction, but simply a legal requirement.
Navigation data
At the close of this edition, SEAT has two different versions of radio and nav-
igation system “SEAT MEDIA SYSTEM 2.2”, one for Western Europe and one
for Eastern Europe, with and without DAB respectively ⇒ page 24.
In normal circumstances, all the necessary navigation data is already stored
in the navigator. The maps stored in the system (Western Europe or Eastern
Europe version ⇒ fig. 1) depend on the country in which the vehicle is sold. SD cards with the different maps offered by SEAT or with the annual map up-
dates can be obtained through the SEAT Technical Service. Please ask your
SEAT dealer ⇒ page 49.

Note
Dirty or damaged navigation data media may lead to problems when copy-
ing navigation information or even in the navigation itself. Store unused da-
ta media in a suitable container or in the original box to protect them from
mechanical damage, heat, humidity or direct sunlight. 
Limitations of the navigation function
Possible errors in navigation
If the navigation system is not able to receive data from the GPS satellites
(dense vegetation, underground garage), it is still possible to navigate us-
ing the vehicle sensory analysis.
In areas that are not or only partially digitised on the data medium (e.g. in-
sufficient definition of one-way streets and road categories), the navigation
system will still attempt to provide route guidance. 
