I am trying to get my maps updated as well, I have one of the early CIC which doesn't have the tick or the i in the circle. I asked BMW to update the firmware and they suggested I don't get them to as quite a few cars have had problems and needed new control modules as a result. I have googled this but cant find any evidence to back up what they are saying.
Has anyone ever heard of a CIC update causing control modules to fail?
