You are correct, you can not play MP3's. This is a common misconception that MP3's burned to a CD create an MP3 disk and has created a lot of confusion on this board. The primary difference between the two is compression. You can only fit about 10-15 CD on a disk versus, oh I don't remember, probably 40 MP3's on a disk.
I have to wonder why anyone would really care if they could get only 15 versus 40 tunes on a CD--given that the quality is no different. To me, the issue is not how many decent quality tunes I can get on a CD, but, rather, it is can I put tunes from different CDs on a CD with quality at least as good as MP3. Please explain to a non-MP3er what the issues are.

mp3 is a way to shrink the files down in size - if you shrink the files down to 128 bits ( the smallest mp3 will allow) then you can several hundred songs on a cd
I could not get 128 to work and had to use 192 and each song averages 4mb - and you can get 70 mb on a cd so I got well over a hundred songs on the cd
with mp3 you can also store in files
for example I made a beatles file and put my favorite 40 beatles songs in it and another file for guns and roses
you could also makes a beatles file and the a subfile withe each album separatley - it also displays the artist name and song title
and there is a random function(I think have not verified yet) that you can just put in the mp3 cd and it will randomly play the songs on the cd
not sure what cda is but if you burn a regular cd it is in minutes and you can only get about 74 minutes on a cd
the mp3 quality is worse than regular cd quality, but I can not tell - but the regualr US stereo also sounds good to me
That is why the ipod is supposedly so good - it shinks the files down to almost mp3 size but the sound quality is supposedly better, but again my ear hears no difference.

The compression between CD Digital Audio and a typical MP3 is actually more like 10 times. The reason you see the .cda file as being only 2KB is because of the way the OS displays CD Digital Audio files (merely as "references" to the real content; this is because a CD audio disc isn't a data CD, but Windows, for example, will "display" the tracks as if they are actual data "files", even though they aren't). A typical track on a CD is around 40-50MB while an MP3 is 3-4MB.
So it's not 15 vs 40. Its more like 15 vs 150-200, depending on the bitrate used.

Thanks das. Your reply totally clarifies what I wanted to know except about the quality issue. Is there any reason at all to think that MP3's would be of higher quality than CDA's--if ripped as WAV files in the first place? If not, then it would appear that the only advantage of being able to play MP3's is because one can get more files on a CD. To me, the higher quality of WAV CDA's, if true, would far outweigh the capacity advantage of MP3's. And, when I talk about quality, I am not talking about perceived quality, I am talking about the absence of information loss.
In thinking about these issues, what would the qualitative difference be if the ripping was to MP3's in the first place and MP3 CDA's were produced? No qualitative difference I presume??? I ran across an interesting read on perceptions concerning MP3's, Pro MP3's, and anther format--which I can't remember the name of now. I'll post a link if I can find the read again.

Here's EAC/LAME info:

Here's MP3Gain info:
http://mp3gain.sourceforge.net/
The advantage of MP3s is file compression and therefore ability to hold more music on a given amount of storage space.

Thanks very much Stream. All that you say helps a great deal. At this point, since my car can't play MP3's after all, I will be burning only CDA disks--where the only point is allowing creation of my own "playlists." In this regard, from what you say, I won't be starting from MP3's. If I truly want quality (no information loss) as high as that as on the original CDs (might also be playing them on home audio--not just in car), then how would I proceed. My best attempt, I think, so far has been to RIP using Windows Media Player's lossless format. But, I think that this format still employs some compression???? So, is there a better starting point? And, are the audio files created using the process I described WAV files. They are identified simply as Windows Media Audio Files on my computer. Thanks much again for your thoughts/help.

It is amazing how can we all be investing so much time trying to sort out what our cars will be able to do or not...
It had to be a software issue...
So, as a software engineer, i know that the answer is really simple as long as we talk to the right guys: the ones who do the damn system. Who are they? Not "BMW guys" for sure that you can reach using our so knowledgeless dealers...
Any clues? Iceman? I will do some investigation on the net...

I know it is not only software. But the guys that build it know the dependencies on the hardware and software versions (or CIP versions). And they also know the meaning of the versions described in the "secret menu".
