    Just one more question. Are the signal ground for D2B and common car ground connected together or not.


    I wouldn't assume that. If you can, opto isolation is always safer I think.

    I agree about opto isolation between PC and CAR but my question was about CAR GND and TX-RX-GND part, becouse 12V from REMOTE HU is used for pull up voltage for transistor, but if there is some kind of isolation between CAR GND and TX-RX-GND for D2B it will not work, tomorow i will take out HU and measure resistance betweeen HU GND and HU TX-RX-GND

    I have pins on 10 pins ISO connector style on HU.

    I am at the moment in stage of collecting peaces and i will probably make first testing on weekend.

    Thanks for help Vince

    I guess your question isn't particularly related to Renault cars, Tuner List head units and CD changer emulators, right ?

    In this case, I would kindly advise you to use the search menu of the forum and look for "I2C display" or something like that for more appropriate threads.
    In case you don't find any result, don't hesitate to start a new thread but please be more precise : What are you missing ? Hardware interface ? Software driver for the I2C display ? Plug-in for Winamp or a Front-end ? Is the I2C display part of your car or is it a stand-alone display ? Make ? Model ? The more details you give, the higher the chances you'll get a useful answer .

    Good luck.

    Wooh... Looks like it doesn't have much in common with what we know.

    The most worrying part I think is that pin 2 is labelled "CD Changer communication data link (+), data" and 3 the same with "(-)" and "!data".
    Unless the guy who wrote this sheet had fun changing the labels to look more cool, it looks more like a balanced signal than a Rx/Tx pair
    Moreover, as there is no information regarding direction, I guess it's a bus type of communication...
    In this case, all has to be started again from scratch and hardware part won't be that easy I'm afraid...

    Do other members share the same feeling?

    yes I agree with that here below is some table list of HU and CD changers


    Megane, Laguna, Clio II Philips DC259, DC279 VDO CH-0600

    Philips (D2B) DC459, DC461, DC594/62L, DC459/62L Philips D2B
    SAT6000, SAT6010

    it is definitely D2B bus, which means that it needs TX-RX to bus interface or
    try and se what happens

    can you share pin layout on your HU and maybe we can see some similarities
    or to rephrase question where did you find that pins on HU have TX,RX labels
    i have been browsing through various documents and did not found it till now

    thanks vicne all what you wrote is right

    is seems that d2b is bus and probably it is different protocol also

    anyway in the meantime i have developed a board for opto isolated version for TUNER LIST HU series and i will put it on the net tomorow

    it will have no use for me but it will save some time to somebody else

    The source I had is here (can't remember where I found it).
    I then compiled and illustrated pinouts for both Tuner List and Update List (with some help) on this page.
