I find some of the comments here to be very interesting but I was told via the Ford web site that my Sync upgrade was to be installed by the dealer. I was given intructions on how to do the update so I wondered why they told me to have the dealer do this. So, I take the car to the dealer and I wait for the install to be done so I can go to work. No joke, 3 1/2 hours later, I'm still waiting for them to finish. I ask why it's taking so long and they tell me the car stops running before they can finish. So I ask if they turned off the auto shut off feature that are in the instructions and they look at me like I'm some sort of creature from outer space. So, I call work and tell them I'm not going to be in, I have the dealer take me home and wait for them to call when the car is done. It's after 4 o'clock in the afternoon when they finally have it done. Unbeleivable! The update is great. It now shows the outside temperature next to the time/date at the top of the screen. The connectivity to the phone is faster. The song being played (either by over the air or satellite) is displayed regardless of what screen is on the monitor. And to top it all off, there's a new screen that has the silhouette of the car and displays the power being used (gas, electric or both? and where the power is going.
