Can't get CD to play in my Jeep

I have bounced my tracks down to a stereo master track via busses, and then bounced that track down to .wav and burned it to disc, but my Jeep fails to read the audio file. I also have the dither plug-in active on the master track. I can put the CD into a computer and the file is there, and plays just fine. I've tried this on two different brands of disc (one is a dvd-r, and one is cd-r). I do most of my music listening in my Jeep, so it's the best place for me to compare my mixes with other CD's. Any ideas?
