A nice little Bluetooth speakerphone is available that takes the focus of fumbling for your phone to just pushing a few buttons on the steering wheel. The Bluetooth attaches to your steering wheel and uses two 2 watt speakers with noise reduction and echo cancellation. Numbers or names will appear on the display showing all inbound calls which lets you decided to accept or reject all by pushing a button. 8 different cell phones can be paired with the bluetooth and up to 600 numbers can be transfered. It has a battery that is rechargeable and has up to five hours talk time with just a charge of three hours with the DC car adapter.
