The Tuneflex from Griffin prevents your iPod Nano from slipping from the dashboard and meeting an untimely death under the brake pedal. It plugs into your car's cigar lighter socket and has a steel gooseneck with a cradle sat on the end. It not only charges your iPod but also provides a line out socket with an adjustable switch for cassete adapters and stereo cables. With the Dock connector you can hook up iTrip FM transmitter or Airclick remote control. The base has a glowing light which tells you the iPod's battery life.
