I have a related question. How can you give recommendations when you don't even know what kind of car he has. I assume it is a Mercedes, but it could be an S class that has a radio from an old 123 or something. He could have a young child that tried to put his engine oil in the radio. Maybe it sits in the sun in sunny Texas and the dash is melting and running into the radio. How about a capacitor in the radio has ruptured and is leaking oil. I would hate to see someone spend a lot of money and time trying to fix something that ain't broke. In my shop, I won't work on a car until I know the year, make, model, and engine. Mistakes are easy to make on cars nowadays so all the information is needed to make a diagonisis. I know you get tired of me making these statements, but good information is VERY important, and without it a lot of mistakes can be made.
