No radio
 

I have a 300CE and my becker radio does not display anything when its on. The car aerial goes up and when you switch it off you can hear the pop of the speakers. It has no display at all. I was wondering if this means its still the fuse or is it internal with the radio. And where would i go to change the fuse. I'm very naive but dont want to take it to a garage especially if its a fuse.
