“Does the USB 2.0 connectivity interface plug into the ipod docing port? I notice an ipod has the same USB 2.0 interface option as the sony MP3 The reason I ask is I have an amp that has the 2.0 interface and was told it's use is for ipod's. And I am curious if i can use the Sony Walkman MP3 with this same docing port to play music through my amp? Thanks Loren”
