My Ride: 2003 330i ZHP
Pin-finding for DIY Parrot install

I know, I know, I should just buy an adapter harness, but the idea drives me crazy when I'm this close.

I've got an '03 ZHP sedan... Business CD (round pin), H/K audio, no nav, factory aux in adapter being used for ipod.

Got a Parrot 3100, so no hope for steering wheel controls, but I would like it to integrate nicely. I searched for several days on here and everywhere else I could look for a good pinout on the wiring harness, figure this can't be THAT tough, right?

Anyway, I've got power, ground, the easy stuff. Got the tel mute wire hooked up right. So when I place or receive a call, the radio mutes just like it should. But I can't for the life of me find which pins I should be using to bring the phone audio INTO the business CD. One pinout document I found placed the Phone input pins on the same 10-pin connector as the CD changer interface; another seems to suggest that it should be on the same plug as the aux in (this should be easy since the aux in connector only has 3 pins populated and adding more is much nicer than tapping into existing wires.

But at this point, I've searched my brains out and haven't found a reliable answer so I'm putting myself in your hands. Can anyone tell me where the phone audio should be coming into the head unit? Or am I way off-base here and maybe the phone audio should be feeding into the amp directly somewhere? I dunno.

Any help would be GREATLY appreciated.
