    Lightbulb Renault "Tuner List" Head Unit/CD changer hacking

    Hi Petri,

    In respone to your question:

    1) What car have you got? I am assuming that you have a reanult car.

    2) You should buy from ebay the head unit with UPDATE LIST because it will match with your Renault stering wheel provided you match the cable right.

    3) You should download the pdf manual that is provide by putput, it makes the wiring easy to follow.

    If YOU have anymore question please e-mail me !!

    Display and Stalk Control Interfaces

    I would like to know if someone has any information on the interface between the update list unit and the display. Specially the physical layer. I've read that the interface has changed. Is it CAN nowadays? I want to use it to control and display iPod Information.

    Thank you,

    Hi everibody.
    Some posts ago, i read about sending text data to dashboard lcd..
    Sure it can't be done through CDC connector, but i believe it is possible through the connection between the HU and the dashboard lcd itself (because usually the lcd writes radio-data text while listening to a fm radi ostation).
    Assuming I have the pinout of the connector (i got a '01 clio) and a pc, how can i send text (i.e. mp3 id3 tags, and so on..) to it? Someone knows??
    I think it should be done (if possibile) using a com or a parallel port and some software (like a winamp plugin..)..

    any help please??

    Thanks

    Car Radio Digital Signal Processor Philips Saa7708H used in this unit, has two digital spdif inputs. Spdif1 (pin25) is used by additional cd changer and, as we all know to eneble it we have to have cdc or an adapter. But spdif2 (pin24) is used by internal cd drive of HU, and this one input is always enabled when compact disc is inserted. So we can use the same circuit with relay like Vince used, but we don't need cdc and any cdc emulators.
    I would like to add some pictures, but I don't where is this option at this forum.

    Nice solution I thought but did anyone else try it? It doesn't work for me

    When I disconnect wire 10 nothing happens, I still get the sound from the CD inserted so this can't be SPDIF :/

    It's the same SAA7708A on my board and surely I have the right wire - any ideas?

    Hi again,

    not being able to believe that cutting the SPDIF input doesn't stop the music I had another look ^^

    I found the wire 10 not going straight to the SPDIF2 pin as said by Michal but via another component to the SPDIF1 pin right next to it in the same corner (red path). But still it goes to SPDIF and comes from the cd drive so why does nothing happen when disconnecting it ... it looked so easy

    Update list - how to activate Aux?

    Hi,
    Amazing stuff, you guys really rock - just spent 1 hour reading this and still have no idea what is going on! I'll stick to my nuts n bolts.
    Anyway I'm trying to get my Daughters Clio (07 reg but last of the MK11's) to accept an mp3 input via 3.5mm jack. It has an update list cassette with integral display - yes cassette in this day & age !, However it has no input (green Iso plug) for aux. nor any Aux in the expert menu. Besides, she wants CD = kids eh?

    So I bought an update list CD HU from fleabay which works fine but stalk controls don't work
    So I bought another update list CD, this time with integral display,model RENRDD 200-00. Checked it had the C2 Aux pin out as shown on here, fitted it with my nice new lead but no way to select Aux on the HU - no, that function is not available in the expert menu.

    Any clues if it is possible to set Aux on, if not what are the pins for? Maybe there is an emulator that would pretend it was a CDC but I doubt if CD has analogue input.

    Sorry if this is a bit off topic but now I'm desperate

    Cheers,
    Dave

    Well, I don't know if it helps, but here are a few thoughts and hopefully they might give you ideas to diagnose the problem...

    1st possibility : there's an error in Michal's information. Although, it seems his setup is functional (I guess he wouldn't have posted photos with soldered cinch without testing it first) and for sure he cut the same wire as you did (the pictures are clear in that regard). Did you contact (PM) him ? Note : the fact that wire 10 connects to pin 25 (SPDIF1) instead of 24 (SPDIF2) may be an error, but as you say, it doesn't matter : if you cut the wire from the CD, you shouldn't hear anything.

    2nd possibility : your models are different revisions and the connector pin assignment has changed (would be surprising, but could explain the difference between your findings and Michal's regarding pin 24/25...)

    3rd possibility : a problem in your setup. Are you sure your switch (I guess you have a switch at the end of the wires soldered to connector pin10) is OK ? Isn't there a loose wire or something shorting wires together ?

    4th possibility : radiation ... WARNING !!!! : the following could damage the head unit if the pin layout is incorrect, and I'll take no responsability - YOU'VE BEEN WARNED :-) !!!! OK, you hear the CD playing when the wire is cut and hanging in the air in high impedance, but what if you ground it (via a resistor to reduce the risk) ?

    5th possibility : an error in Michal's setup that would connect his SPDIF source in parallel with (and not instead of) the internal CD, but if this external source has a much lower impedance, it could "master" the wire and "override" the internal CD's signal

    Finally, you could do your own reverse engineering independantly of Michal's :
    - do you have access to an oscilloscope ? This could give you a better understandng of what's on each pin of that cable. If not, maybe you have a device (amplifier, PC) with a SPDIF input... then you could try (!!!AGAIN : I TAKE NO RESPONSABLITY!!!) connecting it to the different pins of the cable too, and see if and where you're getting an SPDIF signal...
    - at least, could you determine (with a multimeter) which pins are for power and ground ?
    - can you determine (with a multimeter again) if a pin from the cable's connector is wired for sure to either SPDIF1 of SPDIF2 ?
    - can you see on the CD player PCB what chip is responsible for producing SPDIF output and to which cable pin it's connected ?
    - as a last resort, you could do trial and error, and cut each wire in turn to see when music stops and if that gives a meaningful error... Maybe inserting a male/female connector with dip-switches in between would be the easiest to debug...

    Well, that's all for now. I can't promise I'll have time to come back anytime soon but hopefully some things above could help you go forward...

    Good luck and don't forget : I TAKE NO RESPONSABILITY (did I say it already ? ;-)).

    Thanks for the ideas, motivated me to have some more looks ... unfortunately I tried to power up the radio not in the car but in the house with a power supply and the nice pin list I downloaded for the tunerlist cd radio had the A and B chambers swapped in the legend so I just burned the damn thing

    But I'll try to get e new tuner list from ebay for another try, quite expensive at the moment, saw them for 40€ already, doesnt look so now


    But the worst thing is there's still a euphonic cd in the drive and I cant get it out ^^
