My car, which was mad just a few weeks ago, definitely has the update. From what I have experienced, it reacts much faster and smoother than ones I have tried in the past. The only hiccough so far is that after reading weather alerts, it won't return to the previous map view. I basically have to go to home, then tap the Nav icon, and all is well. May even be less taps this way, but I'm sure that's not what was intended.
