Oh ok, thanks. Annoying but if that's the way it is then that's the way it is.. .. I'm almost sure one of those labels mentioned and external mic. Oh well, not surprising I guess. Perhaps I'll try take the black frame of the unit and expose the mic and see if there's a cable issue or something. The lighting at the top by the cd slot stopped working a while back. Perhaps there's a dodgy contact there or something.
Thanks for the heads up!
