It's actually fairly simple (as long as you can splice cables and have some basic tools)
The prerequisite for the update are that you must have the current software level or at least 52.4 for your car before you can perform the upgrade
There are two options to do the retrofit.
If all you are looking for is the "looks" of the new iDrive Touch controller you
can simply by the new controller and replace it with your current one.
It is plug and play. However this will not give you the touch features
If you also want to use the touch features you'll have to install the touch control box
The BMW part # is 65829338800 (appr 60$)
I decided to use the ceramic controller and the part # is 65829320290 (~800$)
Once you have the latest software in your car you can start the actual upgrade
You need to create the Y-cable to add the touch controller to your CAN2 bus
You also need the e-sys software to code your car and enable the touch features
In order to enable the touch controller features you need to change the VO
(vehicle Order) to a date after 7/2013 (introduction of the LCI model) .
For the coding piece you need to change the following settings via e-sys
HU_NBT / 3000_HMI / ZBE_TOUCH_INTERACTIVE_MAP to aktiv
HU_NBT / 3000_HMI / ZBE_TOUCH_SPELLER to aktiv
HU_NBT / 3000_HMI / ZBE_TOUCH_BROWSER to aktiv
HU_NBT / 3004_SYSTEM / EINSTELLUNGEN / ZBE_TOUCH to aktiv-Mittelfach
After the coding you can install the new iDrive Touch controller and the control box
The control box has 4 connections (identical to the controller)
From the outside to the inside they are
red, brown, yellow/red , yellow/brown
Basically you create a Y-cable with one connection to the original plug connecting the
iDrive controller and two ends now connecting the iDrive controller and the touch control box
Finding the correct connectors may be a challenge but you can try your local dealer
and maybe they have some connectors from old wiring harnesses , or a PC shop
carrying PC wiring / connectors
All of four wires of touch controller are bridged to corresponding wires of touch-controller.
1 > 1
2 > 2
3 > 3
4 > 4
3 and 4 are twisted pair.
The length from the point you splitted the wires to the touch control device should not
be longer than 10 cm and KCan2_L and K_Can2_H should be twisted to get a better
protection and to avoid interference on the Can-bus
The touch control box can easily be stored in the center console (it's very small)
That's pretty much it .
Overall the upgrade will take no longer than an hour .
