I am first-time Mercedes owner of a used 2006 ML500 with 60K. I have had the truck for 32 days and have had several issues. Alternator went out, front brake router separated. And now, after just getting it back from the garage yesterday, I have static on all my audio sources. You can still here the music, but there is static coming out of all the speakers. Any insight would be helpful.

Frustrated new owner!

Thanks
J
