iTunes comes with the ability to convert music to mp3--look at the 'advanced' menu. Same for burning a CD. Make your selection, hit the 'burn disc' button and it's done. Mine play fine on the car's CD player (but why play CDs in the car when you can play your iPod?
Please see my post #32. I have been all through the 'preference' options. I am computer literate (I used to build PC's). It doesn't work for me. Sorry.
As for why I want to play music on my car's CD player, I don't care to drive around wearing headphones. Also, my wife wants to hear the music when she's along. I understand that there may be a unit that can plug an IPod into a car's unit (or so I seem to recall hearing) but I have no intention of throwing any additional cash at something I've already come to consider a bad purchase. Sorry!
