Hands-free car kits are perhaps the best use of Bluetooth going. They provide both convenience and safety when making phone calls on the road. Features to look for include full duplex calling, one-touch operation, a good microphone that is placed well to pick up your voice without road noise, and easy installation. Many new upscale autos, like the Toyota Camry, have Bluetooth as standard or optional equipment, so all you need to add is your Bluetooth phone. Add-on kits come in two basic flavors: professionally installed units that connect to your car's speakers and power; and standalone models that have integrated speakers and run off batteries or your car lighter.
Parrot EasyDrive
This hands-free car kit has two parts connected by a short wire: a speaker that plugs right into your car lighter for power, and a dash-mount controller/microphone. The controller has a button that turns through various menus and controls volume, and voice dialing direct to your phone. The portable design means you can move it from car to car easily, and take it with you when you travel, and you'll never run out of batteries.
EuroCB SuperTooth II
This cleverly designed car kit is so small it will fit in your pocket or purse, and clips right on to your sun visor. It has a pick-up/hang-up button and volume control, plus a speaker and microphone. The rechargeable battery provides 15 hours of talk time. An AC wall charger is included. We recommend using an AC/car lighter adapter to recharge it right in the car.
