Hi,

Hope this is the right forum. I recently retrofitted a cic idrive system taken from my friend's 2011 328i car onto my 2011 335i. His car has a combox and usb/aux( 6FL) while mine does not have any wiring for tcu or mulf or bluetooth and only has an aux input in the armrest.

I see there is a MMI box I can get or a new screen with carplay but I wan't to eliminate aux input and use bluetooth so I can use my steering wheel controls and retain the oem idrive streaming services like spotify etc. I see these units use the aux input to push audio in? I have the HIFI system but I feel like it does not sound good with aux.

How would I go about wiring it up? My current CIC idrive wiring was spliced into the cic screen connector to retain simplicity so it only comes down to 4 wires to go into the front JBE connector.

Update:

Pulled out the combox wiring harness from my friends car, combox, bluetooth, usb aux, phone cradle, usb/aux fakra cables and mic with mic wire. Planning to retrofit it this week. I want to use the passenger side to place the harness and use the MOST bus on the drivers side. I have pulled the MOST connector also but how would I wire it up? My E90 already has a MOST bus system since it had the connector in the quadlock but I will check to confirm it tommorow. I have the TOP HIFI amp option so there should be a most bus system. How would I use the MOST connection for the combox?

Read the above.

Thanks CTuna. I understand how the loop system works now. Looks like the CIC is the server and the output is the first cable that is lit up.

On another question the phone cradle I pulled has two antenna cables. One that goes to combox with HSD blue port and another that seems like it goes to the roof ariel. Can I leave the roof ariel one disconnected?

No idea

The dont bother with cradle at all
Do not connect second HSD cable, use only one to USB socket.
