Only Navi OR Rearview Camera

Hello, last November we decided for the Granflsnd X. When we wanted to order, however, there was just the new price list and conversion. With the new version of the innovation with lower price, but also much lower equipment, we could only choose between Navi OR rear camera. To get both, we now have to order either a business equipment or the Ultimate variant. We can not approve of this price policy. Can anyone say something about this??? Why is that, after all, it is the second most expensive equipment variant!
