I installed the update last night and the only issue I had was pairing my Samsung phone. I downloaded the update from the SYNC web site and it took 55 minutes to load. I've had limited use so far, but from what I see it's a vast improvement over the earlier version. I like the larger "button" size, layout and increased speed. Both my iPods and my phonebook synched and downloaded in just a few seconds. We'll see how it performs in the long term (or at least until my 2013 Escape arrives) and go from there.
