Question Dash pinouts for HU/phone/steering/phone

Forgive my noob stupidity if this is already posted I've had a good hunt and best I've found is Tharaka's post including pics of the 17 pin Head Unit connection. Great post Tharaka - nicely labelled.

I'm about to install my Alpine CDA-3855R in favour of the stock business CD (2004 Coupe). I've worked out that this will all but kill the bluetooth ULF, but I'll have to live with that for now. Need for the Alpine is the amp & speaker install to follow. Tharaka's pinout guide shows pins 4 & 10 unpopulated - mine has all pins connected, most have a clear function, but pins 4,7,10 & 16 are still a mystery??

16, I believe is the BMW remote amp switch; and 10 appears to be switched 12v for unknown purpose. Can anyone confirm what these 4 pins do?

ALSO: The 10 pin square plug mounted below the 17 pin radio interface has as far as I can tell, 5 pins connected. I have to assume this provides a link for the CD changer, Bluetooth, and steering wheel controls. A fair bit, for 5 channels of information, but no sign of any other means of communication

Does anyone have definitive information on what this does? I'm not worried about the CD changer link, I have an Apline 6-disc to go with the 3855, and will install it with the Alpine (Ai-net?) cable. It's the steering and the bluetooth I'm interested in. I'm looking at either the Alpine 200BT (thanks Technic) or a Bluetooth Garmin, be great to get either of these to use the SW controls

Last, but not least: Routing. Which side for signal path? I must assume there's a main power cable running from battery to alternator at least. Does the main loom share this route? I need a nice free run for several signal cables and of course front speakers. Any help MUCH appreciated...
