W221 S320 CDI
Sound system keeps needing reset
I have an 07 W221 S320 CDI and I have an issue with my sound system. Every time I start the car I get a really bad distorted sound and I have to reset it and the sound returns to normal. How can I sort this myself?

Steve you may have a voice control module dying the slow death ahead of audio in the fiber optic loop. It lives in the trunk on the left side.

So is replacing the module easy enough?
