there's a really good on-going thread for just the CIC controller retrofit:
The short story is, yes it's plug and play, depending on the software version of the CCC you have on your car. It's worked for most people, again depending on post purchase CCC updates BMW has performed, but if not applicable, the best indication is your car's manufacturing date, I think any post 3/2008 builds should be plug and play. Again, read the thread.
