QUESTION
SOLUTION
ANSWER
The TA box is ticked.
However, certain traffi c
jams along the route
are not indicated in real
time.
On starting, it is several minutes before the system begins to receive the
traf c information.
Wait until the traffi c information is being received
correctly (displaying of the traffi c information
symbols on the map).
In certain countries, only major routes (motorways...) are listed for the
traf c information.
The time taken to
calculate a route
sometimes seems
longer than usual.
This phenomenon is normal. The system is
dependent on the traffi c information available.
The performance of the system may slow down temporarily if a CD is
being copied onto the Jukebox at the same time as a route is being
calculated.
Wait until the CD has been copied or stop the
copying before starting the guidance function.
The altitude is not
displayed.
On starting, the initialisation of the GPS may take up to 3 minutes to
receive more than 3 satellites correctly.
Wait until the system has started up completely.
Check that there is a GPS coverage of at least
3 satellites (long press on the SETUP button,
then select GPS coverage).
Depending on the geographical environment (tunnel...) or the weather, the
conditions of reception of the GPS signal may vary.
This phenomenon is normal. The system is
dependent on the conditions of reception of the
GPS signal.
The route is not
calculated successfully.
The exclusion criteria may confl ict with the current location (exclusion of
toll roads on a motorway with tolls).
Check the exclusion criteria.
I receive a speed
camera alert for a
camera which is not on
my route.
The audible speed
camera alert is not
working.
The system announces all speed cameras located in a conical zone
forward of the vehicle. it may detect speed cameras on nearby or parallel
roads.
Audible alerts are not active.
The alert volume level is set to minimum.
Zoom the map to view the exact position of the
speed camera.
Activate audible alerts in Navigation Menu,
Settings, Set parameters for risk areas.
Increase the speed camera alert volume.
