TThanks

Hi Gwyn-R, 

Unfortunately Apple devices won't play MP3 files so they must be converted into a suitable file format first using iTunes. Do you have access to a computer that you can sync your iPod with? 

The best way would be to download the audio lessons onto a computer, then use iTunes to convert the files and move them to your iPod via syncing. I hope that helps!
