I think Green Day's "American Idiot" was the first one we found that had the audio titles that worked.

Mostly thought we use our Ipods, we bought a power adaptor and FM transmitter for them (~US$100) - they sit in the armrest cavity and work great (why is that cavity not quite wide enough for CDs stacked in it all the way down it's length ... OK at the back but not at the front ... a few more mm and it would be OK, what were they thinking?)
