Help identifying this sensor on rear view mirror

Hi, I'm trying to identify what this sensor does in the car. It's a 2016 x3 xDrive 35i, I thought it might be for ACC, but I don't have this option as I have the cold weather package and M sport. Could it just be installed but not connected?



Thanks in advance.

It broadcasts your rate of speed to the state trooper following you.

My 2016 x35i has the same box with the vent holes but not the larger square hole. I have the Tech Package and Driver Assist Plus, so I have the camera that reads the speed limit, land keep and collision avoidance. Maybe also a rain sensor in there too. Is there an open spot in the window opposite the box to house a camera? Might be something that could be added who knows.

That could be the high beam assistant.

That's exactly what the camera does, it can also be coded to display speed limit on the idrive.
