I have a 2018 440i GC that I bought one year ago. During my first oil change today, I wanted the full navigation map update. I know I get the regional map updates for free, and that seems to be working. After $150, the BMW service center did the full map update. It went from 2017-2 to 2018-1. But I have seen various forums that talk about versions 2018-2, 2018-3, 2018-4, and even 2019-1. How do I know that I have the latest map update possible? BMW Genius couldn't answer that question. They just referred me to the BMW service center that just did the update..... and I know what their answer will be. I can't find anything on the internet, BMW ConnectedDrive profile, or even the BMW store. I would like to have something official from a trusted website or documentation that shows what the latest map version for my BMW should be. That way I can go back to the service center and have them give me the latest map update.
