WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
During radio reception, the digital radio signals are received by the antenna system and transmitted to the remote digital audio receiver (RDAR) (16/145) where they are decoded. The remote digital audio receiver (RDAR) then transmits the signals onwards via the MOST network to the infotainment control module(ICM) (3/281) and the integrated audio module (IAM) (16/1) or the audio module (AUD) (16/105) depending on the vehicle configuration.
Remote Digital Audio Receiver (RDAR) uses the signal, satellite or terrestrial, which is strongest at the time.
