Maps - Vauxhall Astra GTC Infotainment Manual

94 Navigation
Nearby traffic problems are also
reported if route guidance is not
active.
If route guidance is active, the system
continuously checks, based on the
traffic information, whether it would
be better to recalculate the route or
take an alternative route taking into
account the current traffic situation.
The activation and deactivation of
dynamic route guidance, as well as
criteria for the calculation of the route
and other settings for navigation, are
made in the Navigation options menu
3 85.
Dynamic route guidance only works if
traffic information is received via the
RDS-TMC traffic information system.
The possible delay due to a traffic
problem calculated by the
Infotainment system is based on data
that the system receives via the RDS-
TMC station currently set. The actual
delay may be different to that
calculated.

Maps

All map data required for use of the
navigation system is stored on an SD
card provided with the Infotainment
system.
Map SD card
The SD card reader of the
Infotainment system can only read
the SD card provided specifically for
use with the vehicle's navigation
system. The SD card reader cannot
read any other SD cards.
Due to production date of the map
data on the SD card, some new roads
may not be included, or some names
and roads may differ from those in
use at the time the map data was
produced.
To order additional SD cards or an
update of the map data, contact
a Vauxhall Authorised Repairer.
Replacing a map SD card, see below .
