Renault "Tuner List" Head Unit/CD changer hacking - Controls

And as I promised the eagle schematics. It was done in a hurry, but it will do. Of course check the footprints of the resistors and mostly the capacitors before you build it.

No, it's OK for me : "Tuner List HU/CDC hacking" is the name of the thread :-)

The only thing is that some might find this thread is too heavy, but I think it's better to have all centralized in the same place.

Worked VDO headunit CD CHANGER simulator by Atmega8L

BUT, i have test it in Models before 2000 which have an analog CD Changer audio input, I don't can it work on the models with SPDIF input.

Vicne: thanks that's great!

Foldesa: thanks too, you're really amazing. I know the cs8406 can take i2c by switching something, and I did notice they advise some other diagram for the line input, but you're saying the mc33202 op amp wouldn't work ? Or just that I have to figure out the correct way to connect it to the cs5343 ?

I called to my local Renault dealership asking about Line-out, but they don't have electrical scheme of "Tuner List" because Renault do not share these things

...I thought, if you are examing these HUs, you could know...?
help?

If you want to change 5330 to 5343 then you have to do several things. I don't think we should discuss it here, instead send me a private message and I'll tell you about it. The forum is far too big now, so I think it would be wiser to add only the conclusion

But I will help you

Done, you're right, if we manage to pull this out, we'll post the alternate schematics here.

Great !
What model is this? Can you give us the make/model of the car and the make/model of the headunit ?

As far as I know, it does NOT work on models before 2000 (I mean without spdif). Is that your observation too ?
