i also have the icfcs10ip and at the begining everithing was ok but now it doesn´t work playing music from ipod or iphones. I´ve tryed with ipod touch 4, iphone 4, and ipod nano and with all them it only charge the device but there´s no music. I can listen the music but from the device, not from the sony. The radio works and the aux input also works so the volume is ok. Any recomendation
