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 information 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.
