Setting up the BTC455 in my car was simple - I found a convenient place to stick the main disc unit on the side of the center stack using the included double-sided tape. The disc end of the BTC455 includes Bluetooth electronics and a microphone for making hands-free phone calls. Blue and red LEDs, shining through the surface of the main button, serve as indicator lights for pairing and other functions. The device features a large button on top, and two smaller buttons on one side. At just over 1.5 inches, it is small enough to attach discreetly to a car's dashboard or console with the included Velcro pads.

The main component of the BTC455 looks like a thick disc. The BTC455 maintains all the features of the previous model, but adds support for two simultaneously connected Bluetooth devices. Last year, I looked at the Kinivo BTC450, and was impressed by its simple design and functionality. The BTC455 plugs into a car's stereo, transmitting music and phone calls from your phone through the car's speakers. Almost every new car comes off the factory line with Bluetooth hands-free phone support these days, but if you want to upgrade your old car with Bluetooth, the Kinivo BTC455 Bluetooth Hands-Free Car Kit may be the answer.
