MP3 study for CFP exam?

I have the CFA charter, and was thinking of taking the CFP exam. I know I have read that I don't need it if I have the CFA, but I think getting the CFP will give me knowledge about HNW planning and will be helpful in the advisory side.

My quesiton is this: does anyone know where to obtain study material in audio format - MP3/CD, etc? I have close to an hour commute each way to work and want to use that to study. I asked CFP Board and they have nothing- looks like Kaplan doesnt either. Only place I have seen offering something is Keir Success and I don't know anything about them.

Thanks!
