AFAIK, there were 2 releases for the updated iDrive controller and new CIC Navigation for the 3-series...

1. Car Information Computer (CIC) using 80GB hard drive with Professional navigation only (larger 8.8" widescreen) - from September 2008 production.
(Not sure, but I think the old DVD-based Business navigation also shipped with the updated iDrive controller from September 2008 production?)

2. CIC Basic using Flash memory (NAND chip similar to an SD card) with Business navigation only (smaller 6.5" screen) - from second half of 2009

You can check the car's build date under the bonnet (at least you can for sedans). For the E92 335i, Professional navigation is a standard feature (as opposed to optional extra). The new CIC/iDrive2/Professional combo also includes a DVD drive (I believe the old system included 2 drives, a DVD + a CD drive).
