WHEN CONNECTED TO PC IT DISPLAYS OK TO DISCONNECT

I would like to advice you that, Install a iTune software & just synce you ipod with your PC files & it will get music. Copy paste is not working in ipod you must have to synce ipod to play music.

Thanks.

not likely the new 4 gen Ipod has different pin set within its dock connector system for the video output which has made many 3rd party accessories no longer able to charge the ipod but it will still play music
