Mach 460 and cd-rw discs

Yeah, must have been the wrong format. I used a burning program I never tried before and didn't see an option to set the format.

I just burned a couple cd's with Nero in the music format, i'm gonna try those out on the way to work in a bit.
 
Well these new ones that I recorded with Nero in music format didn't work either so I don't know what I'm doing wrong. It says 'Bad Disc' on the head unit. The discs aren't bad, they work on my computer and home stereo.
