Professional Head Unit pinout

Hi guys,

Looking for a pinout for the professional head unit for my e87 and since the e90 head unit works on the e87 I assume the pinout on the back of the head unit is the same?

I need to find out which pin is always live (and which can be used for ground) while the car is unlocked (even if the key is out) so that I can connect the power cable of the Dension Gateway 500 to it. The car has no CDC prep so no cables I can tap into there.

Edit: found this: http://www.e90post.com/forums/showthread.php?t=319976 is that correct?
or is pin 16 the 12v accessory one that should be used as per below?
