Frequently asked
questions
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.
► Activate the "RDS" function in the upper bar
to enable the system to check whether there is
a more powerful transmitter 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).
