The AM/FM tuner module (AFM) has the task of receiving radio signals on the AM or FM wavebands then processing and transmitting the signals onwards on the MOST network.

There are four different market configurations:

Europe
USA
Australia
Japan.

In 4-door vehicles the control module is located on the parcel shelf. In 5-door vehicles the control module is located under the right-hand rear side window.

The control module uses optical serial communication to communicate with other components on the MOST network. This means that all communication with the control module is via the infotainment control module (ICM).

Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using VIDA (Volvo scan tool) via the data link connector (DLC) in the vehicle.
