Where go usb cable from MULF2HIGH ???

Hello from France dear Bimmer'driver !



I'm New on this forum with à great community, and professionnal in coding, retrofit :)



My first post it about m'y armrest usb port :

From factory, i've 6NF and 6FL with Mulf2 high in association with CIC iDrive.



I've retrofited a combox bn2000 telematic (i don't care of telematic fonction, it's Just because télématic was less expansive than média)



I wired the combox correctly and update my iDrive to C1A. All work fine, ad2p, phone, contacts, bmw live, internet... Excepted USB in armrest !



Since 2 month i search why... But nothing !



At first, i think it's was the usb hub, but under thé driver seat... nothing !

So, i've decided to follow the câble of the phone cradle.



He is composed of two cable, one antenna and an another for phone connection with only 3 wires pluged on little adaptator and go to the front of center console.



With WDS i've finally determinate my cradle was directly wired on the mulf2...



So the usb hub is not required and it's for this it's absent.



But when the usb cable on combox is plugged, nothing append ! No power, no data on phone, usb Light !



I try to follow the cable from trunk but i can't continue after rear of seat.

The connector is black With angle on combox, and my usb in armrest is White So i think is not the same cable... But where is the end ?



I tried to code usb hub M in combox, nothing.

I've seen in CIC trc file the line CCDM USB : nicht activ



What is it ?



Usb armrest is good, because at first i've plugged an bn2010 and usb work properly, but the rest not...



Thanks in advance dear friend !
