No audio




So it's not trivial to gues right!
- the head unit
- the main amp
- AUX interface
- and MOST fiber ring
- none of which are cheap or simple to replace!
Use a good MB scanner to pull faults.








that's good news! This means your amplifier is not toasted.
I bet on it's a logical issue...
something on CAN-B ?
Media interface module ?
head unit itself ?
Does the internal control unit reset mean anything? Both the head unit and media interface module have errors
