Z4 E85 audio wiring

[tchides]

Hello,
I would like to change the original radio with a modern one on my 2007's Z4 E85 (phase 2).
But of course the wiring of the new radio is generic : I have the description of each wire of the new radio, but not the wiring on the car's side.

Picture of the wiring of the car :


I have the following options :
S662 - Radio BMW Business CD
S672 - Cd Changer Bmw For 6 Cds
S677 - HiFi system Professional DSP
But NOT the screen & nav on the top of the dashboard.

I've searched through the forum but I didn't find a post describing the wiring.
Does anybody have a wiring diagram or a description of what is the use of each cable ?

Thanks !

Hello
So I bought an adapter especially made for E85 models :

But it doesn't work... The new radios powers on correctly at 2nd key position, but I have no sound...
I checked twice the wiring and it's done (the adapter and the new radio have description sticked on each cable).

Has anyone faced the same issue ?
