My brother and I each bought a 2007 C280 4matic a few months ago. A week ago his radio went dead ie. no sound from AM/FM. When he selected CDC, the panel displayed "No CDC" even though the CD cartridge was there. However, the problem disappeared later in the day.

Today, the same problem happens onmine... no sound.Imade sure it was not the mute button.I also got the "No CDC"msg whenI hit CDC. However, the problem has not gone awayevenafter I restarted the car a few times. Anyone else has the same problem?
