The Sony Audiophile DAB radio which was available as an option for the Mondeo MK4 and S-max/Galaxy is completely different than the Focus Sony radio's. The Sony Audiophile DAB radio has no built in amplifier. This radio has an extra (grey coloured) connector on the back of the radio which needs to be connected to a seperate amplifier module. Without this amplifier module you will not have any sound.
The radio shows "Unconfigured Mode" because the radio is not configured correctly for your car. As far as I know it is not possible to configure a Mondeo MK4 radio for a Focus MK2 because the communication protocol of the radio is different.Go to the full post
