Mercedes C Klasse Radio Reception Problem

I had a similar issue with my C Klasse. Check the antenna connections first. Radio interference can be tricky.

When you say antenna connections, are you referring to the connector at the base of the antenna on the roof, or is there another connection point I should be investigating? Any specific areas prone to corrosion or looseness?

Mine was the one near the antenna booster. If that doesn't help, you might need to visit a workshop.

You nailed it. I checked the connection to the antenna booster, cleaned it, and the radio works now. Corrosion seems to have caused the signal issue. I'm off to celebrate with some tunes. Thanks for the advice.
