Hi again Ted
Yup - makes all the difference...chuckle...
OK - now that you've got an MP3 somewhere on your computer, it can be converted to an audio file using SD Jukebox software on your computer which will then transfer successfully to an SD Card and you'll be able to play it in your KN7000 using the buttons in the silver area where you insert your SD Card.
Ted - next question - do you have SD Jukebox software on your computer and do you know how to use it?
