Radio Reception
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. 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) (16/94) 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.
