RBDS functions
Radio Broadcast Data
System - RBDS
This feature, which may not be available in
your area, functions only with FM broadcasts.
The radio in your car is equipped with an
advanced system allowing information from
broadcasters to be transmitted visually, as text,
together with the audio signal. This informa-
tion is then decoded by the radio and made
available for several new and unique features.
The RBDS or Radio Broadcast Data System
operates in the FM band only, and the
information transmitted is supplied exclusively
by participating broadcasters. Volvo has no
control over the accuracy of the data or
information.
Coverage by local broadcasters may be limited
at this time, but as the technology and benefits
grow, you will find the radio in your car is
equipped to take advantage of this system.
PI (Program Information) Seek:
When an FM station has been stored as a
preset, the radio also stores RBDS program
information if it is available. When the preset
is selected at a later time, the radio tries to
access updated program information. In weak
signal areas, there may be a delay before the
station becomes audible. During this delay, “PI
seek” will be displayed and there will be no
sound.
PI seek can be interrupted by pressing EXIT.
Radio text
Certain RBDS stations broadcast program
information, which can be shown in the
display. The text will be shown twice in the
display.
To start this function:
Press the FM button for several seconds.
To deactivate this function:
Press EXIT briefly.
)
Alarm
Alarms bulletins are transmitted automatically
by certain RBDS stations. The function cannot
be deactivated.
”Alarm!” is shown in the radio display when
an alarm message is sent. The function is used
to warn motorists of serious accidents, etc.
