Combox Retrofit

The Weegie · 09-07-2022, 03:56 PM

Hello Folks,

I have been a reader since i got my E90 a year ago, and this place is amazing.

I have a 2005 3 Series E90 SE which previously was a NON Nav car. i have since retrofitted the CIC Pro nav system into my car

Things i have fitted are as follows

CIC Screen Wide, CIC Pronav HU (one with HDD) and most obviously the New Dash,

I do not currently have a COMBOX and my car was never fitted with a TCU or a MULF.

This brings me to why I'm making this post, i would like to retrofit a COMBOX to my vehicle to have the Bluetooth audio and hands free system, however during my research the only retrofits i have seen have been swapping it from a TCU/Mulf to COMBOX not a complete retrofit

I have seen a few of the BN200 COMBOX's on Ebay with some of the harnesses attached, however what I really need some assistance is what needs connected to where and what other cables i would need to buy (specifically the ones with the FAKRA connections)

my vehicle was prepped for the CD changer in the boot so i do have a most connection in the boot that's not doing anything at the moment so im hoping i can use this to connect to the COMBOX, alternatively I could find some place under the dashboard and connected it there somewhere.

Any assistance you amazing people could provide would be greatly appreciated and apologies for the absolute essay that I have written here I'm just trying to include as much detail as i can think of

I did pickup a TCU out of a Scrappie so even if i need to start with that then move onto combox i have that option too

I'm in the same situation, made a thread here: https://www.e90post.com/forums/showthread.php?t=1965735

I've got the Sat prep wiring in the trunk already that has the MOST wiring and a few other things that I may be able to use for the retrofit.
