Update was successful and there was no need for calibration, worked on the first drive. Headed for the freeway abou 2 miles from the house and tried Autosteer with mixed reaction. It seemed to bounce in the lane quite a bit (the IC graphic was even worse, super jittery) and it surprised me how much resistance there is to the steering wheel, you really have to put some force on the wheel to correct the steering or change lanes (at which point is disengages). I think I was expecting more of an experience like in my wife's new E300 where the system does not activate if you do a lane correction, or even a lane change, and there is much less resistance to the steering wheel. Her car also has no restrictions on road type or speed of any kind (even on surface streets) but it does nag the hell of out you every 20 seconds or so.
I wonder how long the 45 MPH limit and the freeway limit will be in place...a couple of weeks?
