The dealer could not upgrade my CIC navi software from 2018, they had try it multiple times one more than one occasion. There answer was, we could try updating the firmware from the CIC at my own risk.
I sad I will look in to it, because I want no risk of a non working system and a big Bill.

So I went to some software Guy today, after 45 minuts waiting it was ok in one time, I have now the 2024-1 premium running.
