Thanks for that video, which brings up some interesting points.
Did you notice the warning triangle on the left side of his instrument screen, and the the yellow exclamation points on all sides of the car on the left of the media screen? Earlier this week I got into my car and had that same warning with an indication that there was a parking sensor malfunction. Also strangely when I pushed the dashboard button to pull up the Parking functions on the media screen, I got the same initial screen that you see on the video, with the 2 choices. This is the ONLY time I've ever seen that screen. I had to shut my car off, get out and lock it, and get in and start it again to get the parking sensors to work, and that main Park screen disappeared and hasn't occurred since.
In that video the parking sensors clearly indicate a malfunction, and I'm assuming their function is critical to the Park Assist feature, so a lot of unanswered questions here!
For the record, my car is two weeks old and my software version is 1880, Hardware H56, USA car.
