I installed the CIC/Combox today using information from this thread (thanks mdrobc13) and Patryk. It took me about 3 hours for the install. Coding took another 2 hours given the abundance of options in my car.
We didn't get a chance to install the 2012 Nav. That has been set for next Saturday. The PnP was brilliant and life made easy by the details in this thread. The guy doing the coding was such a pro just watching him remotely take over my PC and doing the magic was mindboggling.
Thank you once again for a very informative thread. Patryk and the team provide an excellent service to the BMW community, and Patryk, thank you once again.
As someone pointed out, no need to trade in the car and lose a lot of money for this CIC/Combox feature. The car is like new, and I have internet through BMW Services. Can't ask for more. Cheers to all. One happy chappy
