Mercedes AMG GT Audio System MOST Bus Fault

I had a similar audio system issue with my AMG GT. No sound, sat nav dead, the whole deal. It was like the car's brain was having a total meltdown regarding anything audio-related. The MOST bus is like the car's central nervous system for data transmission, especially for audio and navigation. When one control unit glitches, it can disrupt the whole network because of how the fiber optics are daisy-chained. Did your car diagnostics point to a specific control unit?

Thanks for the information. The car diagnostics did identify a fault within a control unit on the MOST bus, but the specific unit isn't clear. Could you say which control unit was defective in your case?

I can't recall the exact control unit that failed. The workshop did thorough diagnostics and replaced the faulty part. With your symptoms and the error code, it's best to see a specialist familiar with Mercedes' audio systems. Fiber optics can be tricky, and special tools are often needed to properly diagnose the fault.

I appreciate the help. Your advice guided me to a solution. A specialist visit confirmed a faulty amplifier control unit on the MOST bus. Replacing it fixed everything. Thanks again.
