On my E320 wagon, whcih i just acquired, there is a sharp static "pop" when radio is turned off (maybe when turning on too, can't remember as I write this) or station selecyion buttons are depressed.

I've got the cover off the speaker and am about to attempt to remove the speaker, thinking maybe a wire was loose, but then had a thought...I don't know what I'm doing and there may be no way a loose wire, etc., at the speaker could be the problem.

Any ideas you could send my way would be appreciated.

Thanks,

Allan
