12► Activate the audible warning in the
"Navigation" menu and check the voice volume
in the sound settings.
The system does not suggest a detour
around an incident on the route.
The route settings do not take account of
TMC
messages.
►

Configure the "T
raffic info" function in the
route settings list (None, Manual or Automatic).
I am receiving a "Danger zone" alert which is
not on my route.
As well as providing guided navigation, the
system announces all "Danger areas" positioned
in a cone located in front of the vehicle. It may
provide an alert for "Danger areas" located on
nearby or parallel roads.
►

Zoom the map to show the exact location
of the "Danger area".

You can select "On the
route" to stop receiving warnings or decrease the
warning duration.
Certain traffic jams along the route are not
indicated in real time.
On starting, a few minutes may elapse before
the system begins to receive traffic information.
►

W
ait until traffic information is being received
correctly (traffic information icons shown on the
map).
In certain countries, only major routes
(motorways, etc.) are listed for the traffic
information.
This is perfectly normal. The system is
dependent on the traffic information available.
The altitude is not displayed. On starting, GPS initialisation may take up to
3 minutes to receive more than 4 satellites
correctly.
►

W
ait until the system has started up
completely so that there is GPS coverage by at
least 4
satellites.
Depending on the geographical environment
(tunnel, etc.) or the weather, the conditions of
reception of the GPS signal may vary.
This behaviour is normal. The system is
dependent on the GPS signal reception
conditions.
My navigation is no longer connected.
During start-up and in certain geographical
areas, the connection may be unavailable.
►

Check that the online services are activated
(settings, contract).
Radio
The reception quality of the radio station
being listened to gradually deteriorates or
the station presets are not working (e.g.
no
sound, "87.5" MHz is displayed).
The vehicle is too far from the selected station’s
transmitter, or no transmitter is present in the
geographical area.
►

Activate the "RDS" function by means of the
short-cut menu to enable the system to check
whether there is a more powerful transmitter in
the geographical area.
The aerial is missing or damaged (e.g.

when
going through a car wash or in an underground
car park). ►

Have the aerial checked by a dealer
.
The surrounding area (e.g. hill, building, tunnel,
underground car park, etc.) is blocking reception,
including in RDS tracking mode.
This is a perfectly normal phenomenon, and is
not indicative of an audio system malfunction.
I cannot find some radio stations in the list of
stations received.
The name of the radio station changes.
The station is no longer received or its name has
changed in the list.
Some radio stations send other information
in place of their name (the title of the song for
example).
The system interprets these details as the station
name.
►
Press "Update list" in the "Radio stations"
secondary menu.
Media
Playback of my USB memory stick starts only
after a very long wait (around 2 to 3 minutes).
Some files supplied with the memory stick may
greatly slow down access to reading the memory
stick (multiplication by 10 of the cataloguing
time).
►

Delete the files supplied with the memory
stick and limit the number of sub-folders in the
file structure on the memory stick.
There may be an extended pause after
inserting a USB stick.
