No on-board computer with Fun and Ambiente – but connection does?

I noticed something strange at the Ford Focus Fun (and at Ambiente). Why does this variant not have the possibility to purchase a computer on board? At the same time, the connection (whose savings are expressed in relation to the ambience in the brochure) has such a standard. Is this a printing error in the brochure for Ambient and Fun or is there other reasons that these models cannot be given a computer on board, the connection (which also exactly o how ambient and fun still allows the 80hp engine) but already? [and a temperature and consumption indicator should not be such an exclusive accessory that you have to take a much more expensive equipment variant for this]
