Any Suggestions?
I have a 2000 bose system and all I get is error across the head unit when trying to play. I'm writitng with a yamaha 24x burner on 24x certified discs as well as generic discs. None will play in the headunit, but they will play fine on the computer, in the home theatre and the alpine head unit in the other vehicle.

Or even slower...
In general, the slower you burn the cd, the better and/or more reliable performance you'll get. (to a point) 24x burning is at the cutting edge of technology right now, so it's not really surprising it's causing problems, especially in audio cd players which are notoriously more finicky than computer cdrom drives.
Agravic is right. Try burning at a slower speed. Heck, if all else fails try burning at 1x.
On that note, there have actually been quite a few cdrom benchmark tests performed (by various benchmark websites) with discs burned at various speeds. (I have duplicated these tests at home, too.) It has been shown that discs burned at higher speeds will perform slower in read tests than the same discs burned at slower speeds. And in general, burned copies will perform slower than the original disc.
However, as burning technology gets better, the performance difference between the original disc and burned copies becomes closer to zero, especially at the lower burn speeds. But anytime you burn at the limits, you risk performance and reliability problems.
If you wish, I can explain why this is, but I won't go into right now as I don't think most people have even read this far, nor do they care.
But I'm totally obsessed with making perfect burns, so I've researched this topic a *lot*.
I'm also totally obsessed with getting perfect audio rips to WAV files for making mp3's, but don't even get me started on that! You'd be surprised how much difference it makes to rip an audio track at low speeds vs high speeds! (And the ripping reliability of your cdrom drive can be easily tested. Just ask!)
