Sorry looked over it.

I think I'll try first to let my "spy pass-through" plugged into the HU only, without the CD changer connected, and see what comes from the HU (hopefully something like CristianC saw) then plug the CDC while HU is on (hope it won't fry anything) and see what happens.
The only one thing we won't be able to do without a PIC is let the HU source on "CD changer" forever. On my current setup, it's the case: when I start the car in the morning, control wires make the HU think the CD changer will start playing, then during PC boot I hear nothing (no SPDIF signal) and once it's booted, music starts.
[Well, actually, in my case, that will be possible as I intend to delay the relay switch until PC is booted up, so I'll listen to the CD changer while the PC boots and will then switch to PC output while emulator is ready :-)]
Be carefull when plugging and unplugging something in a car, I blew up my first HU (fortunately I manged to get a new one in warranty) doing this. My carpc wasn't grounded when I pulled the plug and the AUX input sounded like a badly tuned radio receiver when I plugged it in again. Make sure everything is well grounded, including you. You can create a lot of static electricity when shuffeling around on a car seat.
As far as I can tell from reading the logfiles the CDC starts the communication with a type 11h byte with data 60h 06h, then the HU responds with C5h and communication is started. This should mean that the CDC can initiate the start. Try disconnecting only the CDC ACC connection and when the HU is on reconnect it and see what happens. This should tell us if its possible to initiate comms after the HU is turned on. Only thing is, when this works, that the CDC will not be available at power up so you have to change the source each time at startup.

Ok

Agreed.

Personally, what I'm missing most is NEXT/PREV. When I'm alone on the road in "full shuffle" mode and Winamp picks one of my daughter's favourite songs (7 years), you bet I'd like to have easy access to "NEXT" :-)
My son is 10 so his choice of music is a bit more exceptable to me, but I have to agree that controlling the carpc with the Renault installed pilot is a really cool thought and with a bit more effort its not just a thought any more.
