    Damn, this was their reply:

    Dear Giovanni,
    The ARNS001 is designed specifically to add a Sony CD changer such as the CDXT69. Unfortuantely you cannot use this as an Aux input to add an MP3 device.
    You can purchase the ARNS001 from one of our distributors listed on our website.

    Regards
    Chris Brown,

    The guy in this thread bought this RC026 changer and couldn't make it work in a 2003 Clio. Note that connectors are incompatible too, by the way.
    According to this post, the RC026 is compatible with "Clio (up to week 43/1999), Kangoo (week 45/1999), Scénic (46/99), Mégane (48/99), Mégane Cabrio (02/00) et Laguna (50/99)"...
    I was not so sure then

    You "adapted" ???
    Do you have information to assume that all those connectors carry compatible signals ?
    That was the only rear view identical to my radio, so I only assumed that. I wasn't 100% sure
    By the way, is there a model such as Radiosat mentioned on the front of your head unit ?
    No, only philips cd changer control as in the picture here

    And guess what : that was it :-)

    After checking all the connections once again, I discovered that ... I had put a wrong resistor value between GND and pin 4 of the optocoupler (see schematics) : 4K7 instead of the 1K I had calculated. I probably was too concentrated on positioning the components and picked up a wrong resistor that was laying around :-(

    Anyway, I fixed that and made a 200km trip and back, and didn't have any link error. So the only think I'll remember is that the schematics and the software are OK :-)

    Many thanks to all of you who helped me !

    Talking Thankyou Pippiolppi!

    ***** DOCUMENT UPDATED *****[/QUOTE]

    Thank you so much for your advice. It was so easy! And cost me £5 in parts!
    I can now plug any MP3 player in to the stereo in my new Scenic. My mini ISO came with clamps and I just cut a mini jack cable to length and used plyers to crimp the holders in place! Woo Hoo! I bought my ISO connector from conrad-direct.co.uk I will gladly offer advice to anyone trying to do the same thing!

    Pic Emu problem

    Ale,
    I am working with your design but i have a problem,
    i use your schematic and programed the pic with the hex included and with the scope i can see a signal in the RX14 pin but i can't activate the spdif input in the HU,
    something is wrong but i cant find the problem,
    i tested with the pc and a max232 circuit and i can select the aux input but with the pic i can't
    and i tested the pic connected to my pc serial port and i cant see any communication in the hyperterminal
    do i have to do anything else with the pic code before program it?

    You say you have a selection for aux port, then I guess your HU has "Update List" printed on the front.
    If so, I think all the information you need to make this work is contained in this document created by PutPut (cfr this post)
    Hope it helps.

    I'm want to build the stand alone emulator, but where can I by a PIC 16F688? Or can I use a different model of the PIC-family?

    Check the configuration word in the winpic should be 0x30e4.
    if you use the internal oscillator check if the bit time is 104uS.
    adjust value of register osctune (in the main routine) to obtain the correct time.

    Yes you can use any model that include a usart.
