Made for all iPods, including the new iPod Video and iPod Nano, with the exception of iPod shuffle. Transmit your favourite songs from your iPod to your FM radio up to 33ft away. Supports the mini USB port for recharging and syncronizing your iPod with iTunes, it even comes with a free mini USB cable! You'll always know exactly which station you're tuned to as the LCD display is backlit. Setting the frequency is easy with the convenient touch button display. But you won't have to adjust the settings very often -- i703 has two programmable presets for FM frequencies. Enjoy easy digital FM tuning with PLL technology, even in large cities with lots of radio stations crowding the dial. Wide frequency range (88.1MHz to 107.9MHz) with 0.1MHz increments. Connector requires no batteries, drawing its power directly from the iPod, so there's never a power issue to silence your music.
