The following information groups together the answers to the most frequently asked questions concerning the system.
Radio
The reception quality of the tuned radio station gradually deteriorates or the station presets are not working (no sound, 87.5 MHz is displayed, etc.).
The vehicle is too far from the selected station’s transmitter, or no transmitter is present in the geographical area.
The environment (hills, buildings, tunnels, basement car parks, etc.) is blocking reception, including in RDS mode.
This is a perfectly normal phenomenon, and is not indicative of an audio system malfunction.
The aerial is missing or has been damaged (for example while entering a car wash or underground car park).
I cannot find some radio stations in the list of received stations.
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.
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).
Some characters in information about the currently playing media are not displayed correctly.
The audio system is unable to process certain types of character.
Playback of streaming files does not start.
The connected device does not automatically launch playback.
Track names and playing times are not displayed on the audio streaming screen.

When the distribution setting is changed, the balance settings are deselected.
Selecting a distribution setting imposes the balance settings, and vice versa.
There is a difference in sound quality between audio sources.
To allow for optimal listening quality, the sound settings can be tailored to different audio sources, which can generate audible differences when changing source.
When the engine is off, the system switches off after several minutes of use.
When the engine is switched off, the system's operating time depends on the state of charge of the battery.
The switch-off is normal: the system automatically goes into energy economy mode and switches off to maintain an adequate charge in the battery.
