Radio
QUESTIONANSWERSOLUTION
The quality of reception of the radio station listened to gradually deteriorates or the stored stations do not function (no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used by the station listened to or there is no transmitter in the geographical area through which the vehicle is travelling.
Activate the "RDS" function by means of the short-cut menu to enable the system to check whether there is a more power ful transmitter in the geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode. This phenomenon is normal and does not indicate a fault with the audio system.
The aerial is absent or has been damaged (for example when going through a car wash or into an underground car park). Have the aerial checked by a CITROËN dealer.
I cannot find some radio stations in the list of stations received.
The station is not 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 this information as the name of the station. The name of the radio
station changes.
