2009 F07 combox retrofit with Top HIFI.
Hi, new here.
I am trying to retrofit a media combox to my 5 series GT, but I ran into patrol when I noticed that most of my TCU cables seems to go to the TOP Hifi amp instead of the MULF2 unit as almost all instructions say. I was wondering if anyone here had any experience retrofitting combox to this kinda setup?
C214384 is the last 7 of my vin, if that helps.
It seems my MULF only has pins 4,5,17,22,23 and 36 connected. That would mean all the handsfree stuff is handled somewhere else?

Reason: Vin typo.
