With one of our cars, after we did the update, the voice commands didn't want to work. A reboot and a little time seems to have resolved that though. Also, know that the inputs have changed with this update for voice commands and not for the better either IMO. You now need to push the button and wait until it visually recognizes everything you said before you push the button a 2nd time or just wait quietly as it processes your verbal command. Hopefully they change it back to the way you could do it before where you can press, speak and press w/o waiting for it to process what you said. This is MUCH better IMHO especially when you have others in the car with you.
