| The Bottom Line | The BlueAnt Wireless Supertooth 3 is an excellent choice for a portable car speakerphone, especially since it will read out incoming caller ID so you can keep your eyes on the road. | Motorola's latest Bluetooth speakerphone comes highly recommended. However, competing models have an advantage in the voice command department. | The Gogroove FlexSmart X2 is a good option, but not the best, if you're looking for a no-install way to pipe calls and music through your car stereo. | The Parrot Minikit Smart combines an easy-to-use Bluetooth speakerphone with a sturdy smartphone windshield mount and charger, making it useful for both hands-free calling and turn-by-turn navigation when paired with an app. | The Livio Radio Bluetooth Internet Radio Car Kit isn't the best hands-free calling option, but it's a great and easy way to bring Internet radio and smartphone audio playback to almost any car. |
