!!! The terminal was set to display hex format

That's really strange. I'll have to check my exact model number tonight - I should have given it from the start in fact.

The tuner list is made by VDO, not philips. It's possible that the protocol is the same.
Anyway, I repeated my experiment with a divider (18k/18k, what I had at hand, so half the voltage) and still nothing: the receive led doesn't light up this time, but the level is critical, since if I touch the connector it will light up and stay lit until I turn off the HU.
I also tried to connect the tx line (with a diode) to send the start sequence with no success. I think that the usb adapter gives too low a voltage, with a compliant serial port it works but not with the HU (since it probably needs the full 12V). Either that or I fried my HU

So I'll have to wait until someone comes up with a proper conversion circuit.

The Tuner List models are indeed made by VDO Dayton but VDO Dayton took over the car stereo business from Philips a few years ago. And the inside of the Tuner List and Update List is still filled with Philips components. I know because I opened my Update List HU and saw the inside. The DSP used is a SAA7709H from Philips.

Well, there seems to be multiple head units called "Tuner List" :
- The 22DC229/62 that CristianC has
- The 22DC259/62 mentioned on this page
- Mine, which has none of the above indications, but rather RENRDW131-10, from a 2005 Scénic II. See pictures below.

It would probably be interesting to list all of our head-unit models (with car model and year, and pictures maybe).

But the fact is that different models could explain the differences in the protocol. Although I think we can find a common emulator, because as far as I know, the same CD changers can be used on multiple, if not all Tuner List head units.

I have found this table at RueDuCommerce

Very interesting.

So for the ones who speak zero-french, the information above is the compatibility table for the VDO/Dayton CHM 604 MP3 CD changer. Please note that this changer is configurable as digital or analog output. As you can see, it works on "all references" for Renault cars of 2004 and 2005, while it is limited to the given models for previous years.

Please note that CristianC's DC229 is indeed referenced as compatible for Twingo II of 2002 and 2003...

Pippolippi, is your model referenced as compatible ?
