W203 C180 Radio changes station randomly

[charob]

Hi all. This is my first post, re my wife's car. Problem concerns the radio on the Comand system. It has started to automatically change radio station. It also, when turned off, randomly turns on. (My wife is a keen Classic FM listener so when it jumps to Radio 1 - which it always does - at full volume, she's not happy.)
Has anyone got any ideas as to what might be causing this and how to fix it? Is it anything to do with the antenna possibly?
I'd appreciate your help. Thanks.

My CLK with Comand does the same thing, annoying

Have you any idea what causes it (and how to fix)?
