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

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 ^^

holodoc

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

Vicne

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.


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 µP 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.

Can you help me find aux pin on Renault Carminat SH1 Connector x Modus?



Thanks in advance

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).


http://sourceforge.net/project/showf...roup_id=161294

You need tlpicemu.zip on this page.

Please help me...

i get CD error mesage on headunit...

I bought CD renault orginal cd player head unit y2001.I put it in to megan y2000 instead old cassete player headunit, everything works(tuner,display,stearing control) even CD, but the problem is when i insert CD(original or pirate) headunit read how many tracks are on cd and begin to play at first cca 5 sec i can skip track how ever i want, but when i started to listen track i get CD ERR message, cd plays normaly but i cannot change track ,i can only do that at first cca 5 sec, if a go back on tuner, and back to CD i have new cca 5 sec to change track.
What is that error mesage and what is the problem?
