Mini Cooper Audio question

[RIB11]

I am looking to upgrade the standard Front End and Speakers on my 03 cooper, Will any of the Sony or Kenwood units be compatible with the existing factory fit Mini CD changer.

Have any of you already performed this upgrade? and if so what did you use?

Thanks.

New Mini Stuff in Liverpool list a Sony unit as compatible:
