You can try a CD+R. I haven't used the cd player in my Cube yet but I would bet that CDRW's (rewritable discs) do not work either. If I remember I will take some of my discs with me in the morning and let you know if they work. Every mp3 disc I created for my Alpine in my old truck was a CD-R.cubelover222 said:I don't have an ipod, I only have mp3 on a CD-R disc. I tried it, it didnt work. Inside the user manual, it says some disc won't work on the player, like CD-R. Then, what type of disc can I use?
