220QUESTION
ANSWER SOLUTION
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.
Settings, configuration
There is a difference in
sound quality between
the different audio
sources (radio, USB...). For optimum sound quality, the audio settings (Volume, Treble, Medium,
Bass) can be adapted to the different sound sources, which may result in
audible differences when changing source (radio, USB...).
Check that the audio settings are adapted to
the sources listened to. It is advisable to select
automatic sound adjustment (Low, Medium, High).
Check the quality and format of your recording.
With the engine off, the
system switches off after
a few minutes of use. When the engine is switched off, the system's operating time depends on
the battery charge.
The switch-off is normal: the system switches to economy mode and
switches off to prevent discharging of the vehicle's battery. Start the vehicle's engine to increase the battery
charge.
