    Alright then, got a new radio, did the same job on it, same result, no matter what switch position, I hear the cd playing. But I eventually found out why

    It's a bit of both a think I have massive crosstalk in both of the two switches I tried. If the wire is actually hanging in the air sound is dead as it should be, but if I get near the other wire 1 or 2 mm I already hear the music

    So I just cut it and connected my PC and SPDIF-In works like described by michal

    So I just have to find another switch, maybe two on/off switches far away from each other


    edit: alright, if anyone wants to do it this way once, inside put one cable on the one side of the radio and on on the other, otherwise the cd signal will find its way somewhere ^^

    Hello, I wrote from Spain,

    I am new in this forum that I have found looking for like solving my problem with the "Cabasse UpdateList" of my Renault Laguna.

    My problem is that I have activated the auxiliary entrance, with pins 10.11 and 12 of the C2 connector, and has worked perfectly during days, but now the sound is listened to very distorted, I have proven to connect CarPC, a MP3, a PocketPC and everything is listened to bad.

    If I cannot repair it, the following possibility that I have is to connect entrance SPDIF with the CarPC. My UpdateList does not have cd charger that is to say, the C3 connector is right now without using, that it would have to make to use the SPDIF?

    This is my unit:


    Best Regards

    Yes, that's what I meant by my 4th possibility. If you leave the input wire hanging without any actual source, it acts as an antenna. Not an expert in SPDIF, but even ignoring the control bits, the frequency is at least 16 bits x 2 (stereo) x 44.1 kHz = 1.4 MHz, so capacitive coupling should not be underestimated.

    So I just have to find another switch, maybe two on/off switches far away from each other
    Well, I think if you feed the input with an actual source, it should end the crosstalk because the input voltage will be forced by the source...

    I finally found the problem with the circuit

    I was missing a capacitor that made the +5v to the ÁP to ripple so the HU didn't recognize it . Also my SPDIF optical to electrical converter works perfect.



    I have added the copper layout as a pdf.

    Hi all,

    I am new in this topic. I am interested in the PIC based CD charger emulator but I am having a hard time finding the info I need in this very long topic.

    in http://tlcdcemu.sourceforge.net/pic.html the Max232 is only used for programming reason, am I right? If I have a PIC programmer I do not need the MAX232?

    Where can I get the file that needs to be loaded in the PIC?

    Thank you in advance.

    Hi all

    i read the all thread but doesn't find these info, hope you can help me.

    i have a scenic of february 2004 with a tuner list
    i find an update list and try to connect... the radio response to eject and probably ask code but the display doesn't work

    i know this should be a different pin connector between old and new model (this for what i read around the web is due to the old radio was manufactered by philips, new one by blaukpunt)

    due this i find on the net some pin connection scheme but for old models....
    http://tlcdcemu.sourceforge.net/hardware.html
    as i read here "Warning : This pinout is for Philips/VDO/Dayton "Tuner List" and "Update List" head units only. Other models (i.e. Blaupunkt) are known to use the same physical connectors but with a different pin assignment."


    does anyone here have new blaukpunt scheme connection?
    is this translation possible or the new model use different codes to trasmit info to the display and steel whering controls?

    please help
    tnx in advance
    ale

    Yes. But you need make signal from HU - Tx (pin 13) on discrete component. You can get part from simple version adapter (http://tlcdcemu.sourceforge.net/hardware.html) - like as signal Tx (pin 3).

    You need tlpicemu.zip on this page.
