Ipod cable for PCM3 (DIY?)

[SA321]

A. you still need activation code from your dealer for this to work (activated by PIWIS - 10min max) !!!!!!!

B. you should be capable of soldering IPOD connectors (30-pins) or find workaround (like buy IPOD cable from Porsche)

C. I could not find who manufactures USB connector so this DYI is only for IPOD and AUX-in

OEM parts (from TSB 9122) we are trying to replicate

955.642.351.10 console (goes into storage tray between front seats on Cayenne)

997.044.902.43 wire harness (with green connector. it goes into lower right hand side of a big connector if you are looking at the back of PCM)

997.612.471.01 Ipod Cable

To replicate IPOD+AUX part of wire harness you need at one end a green connector as on picture. I don't know its part number so I used blue connector 955.044.902.44 ($2) (on a B&W picture) plus pins 999.650.135.22 x10 ($4-5 total). In blue connector I removed the "bump". If anyone knows the green connector number please tell me. Alternatively use standard IDC 2.54mm 12-pin female connector (will be tricky to plug in but anyhow). On the other end it is IDC 2mm 10-pin female connector that plugs into console 955.642.351.10.

Wires used are from old Ethernet cables which all of us have plenty (8 wires in each but you only need 9)

Pin-outs connections (image attached). If anybody needs IPOD connections they are here http://pinouts.ru/Devices/ipod_pinout.shtml

There is 1.5 kOhm resistor between PCM3 pins 3 and 12. Aux-in is going into PCM3 on pins 2 and 7 through 100 Ohms resistors (one for each channel)

USB is totally separate cable with connectors looking like on pictures attached (if anybody knows where to get them tell me)

Thanks!

So are you saying there is an AUX in on the PCM? Where is it and what version of SW do I need. I assume you are making a cable for this input. Is this a hardline in or FM Modulated?

Is there a way to hook up a charger?

Cheers

Can we use this cable on the CDR-23 radio ?

[SA321]

This is "hard wire" (not FM modulators) for PCM 3. (touchscreen, MY 2009-). There is AUX-in but I dont know if it also requires activation code

It doesn't support charging for 2nd Gen iPod Touch or iPhone 3G. Just so you know.
