    Great, hard and software are almost done and things are starting to work! Time to heat up my soldering station! The only thing is that I'll have a few busy days because I need to start up a project this week and I'm afraid that there will be no time left to work on this one. I'll see what I can do, and I also have a question. Does anybody know if CDC units for Tuner List HU's are compatible with Update List HU's?

    Google tells me that the CAD PI180 is an interface for pioneer head units, if it is so it takes over the display completely, so it can display anything it wants.
    OTOH we can only display what the tuner list is willing to display.

    According to the table Ale posted here, these original VDO changers are cross-compatible. They may although implement a head unit detection mechanism so we cannot be certain until we try, but I'd be very surprised if it wasn't the same protocol.
    Why would they reinvent the wheel and develop different protocols and different CDC just because the HU has a few more features ?
    I'd bet the chances are 99.9% that they are electrically compatible and 99% that they are protocol-compatble.

    Your Google must be better than mine :-)
    Do you have a direct link to more information ?

    Well, the Tuner List obviously can drive the display to show anything (e.g. RDS station name) but unfortunately it seems the CDC protocol they designed cannot carry such free text information. If it did, I suppose their own mp3 CDC would implement it - and it doesn't.
    Now the next step might be to hack the yellow connector protocol - just kidding :-)

    Note that, according to various sites selling interfaces for after market radios, the interface to the display and/or the stalk control actually changed. It doesn't imply that the cdc interface changed too, but it goes to show that they actually do reinvent the wheel from time to time.

    From the datasheet of the chm 604 mp3:

    If available, ID3 Tag and WMA Text such
    as Directory, Artist, Album and Title can be displayed.

    maybe only with certain vdo-dayton head units? (but they don't tell)
