Interesting, I have a 2015 model, and sending destination from the phone or directly from the Google Maps on desktop always worked. I don't even need to connect my phone to the car. My wife's car is newer, and it doesn't connect to BMW Connected services at all. ;(
They have a lot of problems synchronizing, and connected drive is just garbage. It just doesn't work, if I try to use the my phone to send a location to the car's navigation system half the times the application crashes, perhaps with iPhone it's better, but with android (and I have an android one phone, wit android 10) I just gave up on this functionality.
