Griffin iTrip NA22045 FM Transmitter

We've paired a powerful FM transmitter with an intuitive interface, so playing your iPhone or iPod on any FM radio (car or home stereo, boombox, whatever) is super easy. Just plug iTrip into the dock connector, press the SmartScan button and you're set. SmartScan finds the clearest frequency to play your music through your car or home stereo speakers without hassles or wires. And Griffin's SmartSound button adjusts signal strength for the clearest sound possible. Use iTrip's three user-programmable presets to remember your favorite frequencies and recall them with one press of a button.
