DESC: SmartDeck allows you to control your iPod using the built in controls of your cassette player. Using patent-pending sensing technology, the SmartDeck determines which commands the cassette player sends to the iPod. SmartDeck is more than just a cassette adapter for iPod; it achieves truly seamless integration between iPod and cassette deck. Use the cassette deck's forward and rewind buttons to advance to the next or prior songs in the iPod playlist. Pause and stop buttons do what pause and stop buttons are expected to do. Hit the cassette deck's Eject button or switch from Cassette to Radio, and Griffin's SmartPlay technology automatically pauses the iPod.
