It's OK. Having successfully burned the CD the MP3 file of a song I downloaded to use as an experiment to see it is works I simply copy and pasted the song to the USB. So now if I put the USB into the cars USB port it will play even though it is an MP3 file? If I call up "USB" on the cars voice command it should play?
Now I am cooking on gas where else can I download music to Windows Media Player and then transfer to CD-RW or USB other than YouTube because some songs don't allow me to download because of the country I am in.
