Bill:

What equipment and software are you using to burn the CD? The last time we talked, you were using Krystal. I'm assuming you are creating MP3's? I use Nero and let it convert the CD to an MP3 which will reportedly play on just about any newer player... and I usually try the final product on about three players to confirm the CD works fine in all of them. How late is the model truck? It seems like all the newer models have front loading players that will play quite well in the Nero MP3 format but many older players (whether stand alone units or automobile players) seem to have trouble with newer CD software.

Backward compatability (new media on older players) is usually a problem one way or another.

I hope this helps. I'm also assuming you are not using music CDs. Plain CD-R media 700MB/80Minutes usually work fine.
