Give Sync 2 a little credit people!
Comparing my 2014 Ford Fusion Energi's Sync 2 (MyFord Touch) UI to my prior car, a 2013 Chevy Volt and it's Chevy MyLink UI - I'd say Sync is damn nice!
Perfect? No, but not the horrid thing it seems many here are reporting.
One problem, I think, is that the original Ford Sync UI was very bad, apparently having a lot of menus and drill-down to find things which distracts you from driving - probably much like the Chevy UI in function (see below). I've never even seen the original Sync UI so I can't comment on it.
Ford Sync 2 (2014-2015) "Main Menu"
I know, that's a picture from a 2015 Focus, but it the screen looks the same in mine. In the Fusion it's mounted a bit lower, nearer to where your hand can reach the screen. One thing I particularly like about this UI is those color coded, corner buttons are always in the same place, no matter what you're doing in the UI and can be located by the corner bezel of the screen w/out looking away from the road.
Chevy MyLink (2011-2014 model years, not sure on 2015) "Main Menu":
Newer incarnations are, I'm sure, better than this but this is what I used for the 2 years of my Volt lease. I loved most everything about that car but I came to loath this screen and usually just propped my iPhone up in front of it. The menu buttons require you to look down and use fairly precise aim to hit them so it was usually better/safer to just leave it on USB or BT Audio and use the phone. (unless it decided not want to play from my iPhone, which it occasionally did )
That all being said, I'd love for CarPlay to be available as an option on my next car - but the thing that would most attract me would be to have complete choice of apps from either my phone or installable into the car. When my Ford is lease is up in a couple years, if there's a car out there that I can run Waze as my navigation system, that will be a serious contender for my money. (I doubt Apple will ever allow that - but I'd love to be made wrong)
