No Radio (Possible Can Issue?)

Hello, back again with the same W204 issues as mentioned in my last post, I STILL have no audio. I have tried: Using fiber optic jumpers on both the Media Interface Module and Amplifier (Xentry said a MOST ring break on Media Interface and sometimes, the SDAR) I checked both and they both have a red light coming from the Fiber Optic cables.I cleared the codes and still nothing. I am starting to think it might be the CAN Bus connectors that relate to the radio. Can anybody tell me which Can Connector relates to the Radio? Either Driver side or Passenger is enough for me to start to look.

I personally think its either the Media Interface (Multiple tests still says its the constant issue) but Cans are an issue for me since i dont know what the hell anything is, I just need to know when looking at the Topology, what side is which (Driver/Passenger). Below attached at my corroded CAN spots.
