good morning. I have a Montana 700, Navigator 6 and Camper 795. Recently I found that City Navigator NTU is not on my Montana any more. How can I get it fixed? Also Base Camp keep sending messages that City Navigator NTU Europe 2023.1 is locked. There is 2025.1 but I still recieve those messages. How Can I get City Navigator on my Montana 700? Can I download it on memory card that is the sat nav?
