SOLUTIONS
The reception quality of the radio
station being listened to gradually
deteriorates.
The vehicle is too distant from the transmitter, or no transmitter is
present in the geographical area you are passing through.
Activate the RDS function to allow the system to check
whether a more powerful transmitter is to be found in
the geographical area.
The environment (hills, high buildings, tunnels, underground car
parks, etc.) is blocking reception, even in RDS mode.
This phenomenon is normal and does not imply anything
wrong with the radio.
The aerial is absent or has been damaged (for example after going
through a car wash or in an underground car park).
Have the aerial checked by a CITROËN dealer.
When the engine is not running, the
radio stops after a few minutes.
When the engine is switched off, the working time for the radio
depends on the battery charge. The interruption is normal: the
radio goes into economy mode, cutting off in order to save the
vehicle’s battery.
You have to start the engine so as to increase the bat-
tery charge.
The message the audio system
is overheating appears on the
screen.
In order to protect the audio equipment in excessive ambient
temperatures, the radio goes into an automatic thermic protection
mode which results in a reduction in sound volume or stopping
of the CD player.
Switch off the audio system for a few minutes in order
to allow the system to cool down.
Why is one not informed in real time
of a hold-up on the route even though
the option for guidance by traf c info”
is activated ?
When you start up, the system takes a few minutes to capture
the traf c information via RDS-TMC.
Wait for the traf c information to be safely received
(pictogrammes displayed on the map) and make sure
that you use the major arterial roads to have “informed”
navigation.
Only the major arterial roads (motorways and some dual car-
riageways) are featured in RDS-TMC traf c information).
It may happen that a hold-up is not reported by the traf c info
provider.
Why is a diversion not suggested when
I have selected traf c info ?
Do not confuse the “traf c info” guidance option which can sug-
gest a diversion (the “divert” button appears in the window) with
the menus Display of traf c messages” or Reading of traf c
messageswhich affect only the display without recalculating
the itinerary (no “divert” button in the window).
To have “informed” navigation with the detour proposi-
tion, it is essential to activate the guidance option with
traffi c info”.
