The Ford Focus radio is ready for aux input if there is am AUX button in that case there is a plug on the back side of the radio that was to be used with the rear DVD, this is the same radio Ford is installing in the expedition and f series truck and that is why you have the aux, in order to use that for audio input you need to add the interface, its called pie frd04-aux and you can find on most sites that sale auxiliary input or ipod adapters, just do a search for ( Ford aux input )
