I did a full CIC retrofit in my e81 a couple of weeks ago, and here's my "story". My english is not that good I'm afraid, but I'll try my best.
The pictures are mainly taken with my iPhone, so the quality isn't the best.
This is an '08 116i 3-door with business radio from factory, and no CD-changer, bluetooth, enhanced audio system etc. I did however have aux-input which was standard and automatic climate control.
The e81 does also have the storage compartment on top of the dash as a standard.
Since this is an '08 it would have been delivered with the 6,5" flip up-screen if it was equipped with iDrive from factory:
I'm sure the flip-up screen does it's job, but it's starting to get a bit old, so I'd never consider anything other than the CIC with a fixed 8,8" screen.
My homemade to do-list was this:
- Change the center console with one made for iDrive control
- Change the top storage bin with the screen
- Move the climate panel where the CD player used to sit, and mount a few new bezels.
- Make and connect a few cables
After taking the console out, I moved over the arm rest, trim and other bits and pieces from the old and over to the new console.
Afterwards, the CD-player, climate control panel, the buttons for seat heating and the top storage bin removed.
The next step was to install the cables for the screen. The screen requires a signal cable from the CIC, and a combined signal and power cable from the car. The pins to the power/signal-cable is free in a plug behind the glovebox.
Afterwards the screen was mounted on its place.
Then I mounted the wires to the iDrive controller. Since the car didn't have factory mounted iDrive, I had to make this cable as well. The correct socket for this is very hard to reach without taking the dash apart, so I connected it to the same source as the screen, as it barely uses any power. The minus/earth was connected to one of the mountings for the center console, as I didn't want to cut into any of the originally wires of the car. The other brown wire is for the FSC bypass module.
The last two wires for the iDrive controller connects behind the CIC computer.
The CIC uses the same connector as the business CD player, so the only thong that's needed here is to mount the FSC bypass module. It's possible to buy FSC codes from BMW instead of this module, but they cost a lot more.
I also had to connect a GPS antenna.
After all this the only thing left was to mount the CIC back in the dash, I thought.
In my process of planning this, I missed a very small detail. The dashboard on cars with iDrive is not the same as cars without. Even if they have the top storage bin. The difference is the mountings for the CD player/iDrive computer.
After discovering this I actually started to reverse the whole job, but after looking a bit more, I decided to give it a try. I cut away a few plastic bits from the dash, and after a while the CIC computer was on it's place.
I'm not living in Berlin.
When everything was up and running, I made some brackets for the climate panel, and everything's done! The marks is just fingermarks.
Because of this, the fitment is not quite 100%, but it's not far away.
I may change the dash in the future if I'm getting one cheap, but I'll se.
Next thing was to mount back the center console and then code the car.
I've ordered combox and a full Harman/Kardon system for my next project
