    Then it's not the Audi OE CD changer for the B6/B7 - that only reads audio CDs.

    I could be wrong, but won't the head unit determine what can be played? I'd have assumed the changer is just a reader (I.e. it reads 1s and 0s irrespective of what encoding they represent)? So if you both have the same OEM changer, but with different head units, then maybe that's why you have different experience of what can be played?

    Just a thought! :)

    CD changers are analogue units, so they don't provide digits to the head unit but an audio signal - the processor is in the changer I'm afraid

    What's the Audi part number then?

    Every Audi forum I've visited over the last 10+ years has had posts from Audi owners saying:

    - Symphony II internal CD changer plays only audio CDs
    - Symphony II+ internal CD changer plays audio and MP3 CDs
    - glovebox changer only plays audio CDs not MP3 CDs, regardless of the head unit (as already said the Cd changer to head unit connection is analgoue)

    And you're saying different to that...

    Are you 100% sure the tracks are saved as MP3 files and that your burner hasn't changed them to audio format (as that's what Windows Media Player does when you tell it to burn a CD from MP3 files)?

    Try taking one of your "MP3" CDs out of the glovebox changer and putting in your PC - what files are shown? It wouldn't surprise me if they are not xxx.MP3 but xxx.CDA files...

    That's my point, unless you specifically tell Windows to create a data CD it will convert the MP3s to CDAs - so if you just burn MP3s onto a CD you end up with an audio CD and not an MP3 CD.

    No need to chill, I'm sub-zero.

    I concur with Dave on this one, WMP does this 100%, if you dont specify, but as said, quick check is put disc into pc/laptop, check what file extensions are being used.

    Another (quicker) check is for you to just define 'loaded with'. If each disc has 100s of tracks then they aren't audio CDs. If just 10-20 then probably are...
