It makes more sense that a slightly different iDrive CCC was used in '07 when RTTI was added. These slight iDrive differences account for VR being broken on '06 models (only e90s produced in '06) and RTTI broken on '07 models (both e90 and e92s) when v25 is installed.

This is just an assumption based on reading many threads on this and other boards.
Sounds reasonable to me. Of course, my wife's car is an '06 e90 330i -- so we can pretty much kiss VR goodbye if we keep our appointment for the update next week. Very disappointing, because she uses VR a lot.
