I presume you had FM radio selected as your audio source. Can you get audio from any other sources? If not, you may have a break in the fiber optic loop, caused either by a loose connection or else a failed component that will not let light pass. It may be a bit tough to troubleshoot yourself, but try the links in the sticky at https://www.benzworld.org/forums/audio-telematics-forum/2980314-component-level-repair-mercedes-electronics-troubleshooting.html. Unfortunately I do not have a fiber optic loop diagram for your car.
