So, given my idrive controller works fine both within and outside of the CarPlay unit, and the steering wheel buttons work fine controlling the factory idrive, its probably reasonable to assume that the CarPlay box is having issues, not my canbus or wiring. since it would be picking up the idrive controller over the same connection that it should be reading the steering wheel buttons.
