Making your car Bluetooth-compatible is often an expensive and laborious affair. The Blue Ant Supertooth II provides a solution for adding simple Bluetooth capabilities without the usual hassle or cost.

The Supertooth II is a hands-free Bluetooth speakerphone with a magnetic clip that attaches to your visor. It lets you talk on the phone and listen at the same time and boasts a battery life of 20 hours of talk time or 800 hours of standby time. The device comes with integrated volume control as well as a noise-canceling, pivoting microphone arm. You can even pick up and hang up calls directly on your Supertooth II device.

Because there is no installation other than the magnetic clip, the Supertooth II can easily be transported from vehicle to vehicle. It sells for $129.99 at Blue Ant's website.
