Control Module
The system for digital radio reception consists of:
- antenna for digital satellite and terrestrial radio
- Remote Digital Audio Receiver (RDAR)
The remote digital audio receiver (RDAR) has the task of receiving digital satellite and terrestrial radio signals. The remote digital audio receiver (RDAR) uses the signal that is the strongest at that instant.
Frequency range for radio reception:
- satellite transmitter 2320.0 - 2332.5 MHz
- terrestrial 2324.2 - 2328.3 MHz
Remote Digital Audio Receiver (RDAR) has CD quality sound. The quality of the sound is not affected by poor reception, the sound is temporarily switched off instead. If the antenna is concealed by a roof box for example.
A Volvo SIRIUS satellite radio subscription must be activated in order for the satellite radio to function. Activation is carried out by the customer ringing Sirius and giving the serial number of the Remote Digital Audio Receiver (RDAR). The serial number can be obtained in the display for the Infotainment module (ICM).
