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.
how to emulate display info in carputer like virtual display
hu info displaj to carputer...
i have i2c interface
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 .
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...
faceplate software emulateheadunit with remov.faceplate,
now=headunit---->faceplate
?

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

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.

Sure.
Other option : find a more recent 2nd hand HU and use your interface with it... If you find a wreck of a low-end model (Clio, Kangoo ?) with display on the head unit itself, it can probably be changed...
Anyway, sorry for you ... I'll update the compatibility chart on the FAQ page...

seems that it is necessary to open another project which will deal with
HU-s made before 2000, or just as you said switch younger HU-s of corse not w....n (but i like that idea also)
The rear view is identical to that of radiosat 6000. I tried to link directly left and right channel(118-19 and 20(gnd) pins) to a sound source(cd player), but that would have been too easy.
I look to the connects2 interface here http://www.connects2.com/c2search.as...=225&modID=510
but it seems that with my car(CTARNS001), i have to buy the cd changer too.
Do you know if Connection + and - pins are equal to TX/RX pins on tunerlist models?
I know that the only cd changer suitable for my radio is the Philips RC026 and, if i'm not wrong, that is the same for tuner and update list models... so i think the protocol should be the same.
What do you think?
The PIC emulator project mantained by Ale works only on tuner and update list, right? or do you think it can fit for my radio too?
In the end, i bought a tuner list radio for 15€ to make some test... I adapted the connector for the display, clock, tuner and controls from dc594 model to tuner list one, but the display doesn't work, so i can't even know if it's asking me the security code(i think so because even the tuner doesn't work). In addition if i try to push volume, tuner or source keys on the radio I can hear some beeps and nothing more, while pushing the same keys on stalk controls I can't hear any beep... so i think that even stalk controls protocol is different from older models to newer ones.

FROM WHAT I KNOW IT SEEMS THAT THEY ARE NOT (TX,RX 0-12V, and D2B much faster speed and mV instead of volts

THAT WERE ALSO MY IDEAS; BUT ONLY WHICH IS LEFT TO TRY AND SEE

I THINK IT IS ONLY FOR TUNER & UPDATE LIST (FOR UPDATE LIST YOU EVEN DONT NEED IT IT HAS AUX INPUT)

FROM MY EXPERIENCE FIRST NEED TO BE SURE THAT ALL HARDWARE IS READY AND THAN I THINK WITH TUNER LIST IT SHOULD WORK WELL; I SUGGEST TO TRY PC EMULATOR BEFORE GOING TO PIC IT IS EASIER AND MORE SUITABLE FOR DEBBUGING
AT THE MOMENT I HAVE STOPPED GOING FURTHER; I USE CASSETE ADAPTER
AND I AM LOOKING TO FIND PLACE INSIDE ON THE BOARD WHERE THIS CASSETE SIGNAL ENTERS TO AUDIO AMPLIFIER MODULE AND TO INSERT SOME WIRES ON THAT POINT AND BYPASS ALL THESE CD EMULATION ISSUE.
AT THE MOMENT I AM OCCUPIED WITH DWW700M TOUCH SCREEN MONITOR INSTALATION, CAR PC INSTALATION (ONE OLD NOTEBOOK WITH BROKEN LCD WHICH I JUST REMOVED TONIGHT AND USE ONLY AS BASE UNIT), AND GPS, & TV ANTENNA INSTALATION.
BY THE WAY I KNOW IT IS NOT THIS THREAT BUT DOES ANYBODY KNOW HOW TO SAVE TV CHANNELS ON DWW700M or HOW TO SCAN CHANNELS OR ...

Are you sure what they mean isn't that you need a "CD Changer Control" label on the front of your HU - which you have ?

I really doubt it, unfortunately. According to posts above, it looks like previous models used D2B which is bus-type and not point-to-point serial communication...

I'm afraid this changer is not compatible with newer head units. Where did you get this information from ?
The guy in this thread bought this RC026 changer and couldn't make it work in a 2003 Clio. Note that connectors are incompatible too, by the way.
According to this post, the RC026 is compatible with "Clio (up to week 43/1999), Kangoo (week 45/1999), Scénic (46/99), Mégane (48/99), Mégane Cabrio (02/00) et Laguna (50/99)"...

I think the current scope of his project is also limited to the same models

You "adapted" ???
Do you have information to assume that all those connectors carry compatible signals ?

I'm not particularly surprised, you see... Both stalk controls and dashboard display are managed by a central unit and it most probably has evolved too. :-(
By the way, is there a model such as Radiosat mentioned on the front of your head unit ?
