I have installed City Navigator NTU 20221.10. It is unlocked on my BMW Navigator VI and on my Nuvi 3790.
However on the PC it is locked.
I am using the latest version of Garmin Express: 7.7.0.0 which says there was an error with the Install but unhelpfully does not say what the error was.
This is the first time I have had this problem. My 2020 and 2021 maps are unlocked on the PC.
Please can you tell me how do I get it unlocked so that I can use it in BaseCamp?
