iDrive.... HUGE improvement.
I literally wanted to rip my iDrive out on my pre-lci. The nav disc would always stop working when I actually needed to use Nav. It was really slow and laggy.
When I got my LCI iDrive I was utterly surprised at the improvement over the old one. It was much smoother and it always worked, it had offered more features as well.
