when I first got one it had a usb connection and I simply had to right click on the music I wanted to intal then copy and browsed to the usb player then right clicked and paste. That was all I had to do. Good luck.
The model number you give ( seems to be the Argos catalogue number? ) is it this one?: click here if so you should be able to plug it into the PC go to Media Player and just drag and drop files ( music one's) onto it.
