So far, the system only works with Blackberry-format smart phones, but Droid and iPhone applications could come along later.

UVO is voice controlled and has many functions, including asking the car to read SMS text messages to aloud.
"We are connected in our officers, in our homes. It's natural progression to make that connectivity from that element into the vehicle," said Henry Bzeih, a Kia engineer.
Reaction tends to be positive once drivers realize they can put the phone away out of reach.
These systems are fueled partly by market demand and partly by increasing regulation about distraction behind the wheel.
