Opel R15 BT USB Infotainment Manual page 55

If the DAB signal is too weak to
be picked up by the receiver, the
system switches over to the
same programme on another
DAB or FM station.
● If the DAB signal is reflected by
natural obstacles or buildings,
the reception quality of DAB is
improved, whereas AM or FM
reception is considerably
impaired in such cases.
● When DAB reception is enabled,
the FM tuner of the Infotainment
system remains active in the
background and continually
searches for the best receivable
FM stations.
