Thanks, just out of interest, the above these there is another plug called Line in/out but it has a plastic disk covering it . What is this and can it be used for anything.

Hi I have the cable but dont know which socket on my Beocentre 9500 to plug my ipod into: Powerlink, Tv/Aux, tape 2, or Phono? Tv/Aux already has a cable running from the tv into it. Thanks
