Location Of Components, Remote Digital Audio Receiver (RDAR):

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
The quality of the sound does not deteriorate in the event of poor reception, the sound is switched off temporarily instead. For example, if the antenna is covered by a roof box.
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).

Antenna




The Remote Digital Audio Receiver (RDAR) has an antenna. The antenna receives digital satellite and terrestrial radio signals. The antenna is directly connected to the Remote Digital Audio Receiver (RDAR).
The antenna is mounted on the roof of C30/S40/V50 and in the cargo compartment on C70.
There are diagnostics for the antenna.
