Naturally, you need to buy a new Ford to get this service. But it's only a matter of time before other carmakers follow suit, if some haven't already.
Sync uses Bluetooth wireless technology to transfer the controls of your phone to an onboard computer.
You use a button on the steering wheel to make phone calls and listen to text messages, with the car's radio speakers providing the sound.
The system isn't as sophisticated as others on this list: while the computer reads loud incoming text messages, you can only respond using one of 15 generic messages, and there's no e-mail option.
On the plus side, Sync also acts as a GPS device, speaking directions aloud, and can give you traffic, news, and weather updates upon verbal command. (It also lets you verbally operate MP3 players.) Sync is normally a $395 add-on, with no subscription fee.
