iTrip is THE product that introduced the idea of FM transmitters for iPod. iTrip broadcasts the music from your iPhone or iPod to an open FM frequency on the nearest FM radio (whether that"s a boombox, a home FM receiver, or your car radio) so you, and the rest of the room (or car), can listen to your tunes through your own great-sounding stereo speakers. We"ve redesigned iTrip to make it easier to use than ever, and added support for our iTrip Controller App. This industry-first hardware-software integration lets you take full advantage of the Multi-Touch display on your iPhone or iPod. Tap to access your presets or tune iTrip manually. It works on your touchscreen just like the familiar tuning wheel. iTrip Controller is the perfect companion to the world"s most popular FM transmitter, and it"s a free download at the iTunes App Store. Features: * One-touch setup and tuning; Griffin-exclusive SmartScan finds the best frequency for you * Griffin-exclusive SmartSound button enhances sound and adjusts signal strength for each frequency * Micro-USB pass-thru connector so you can charge while playing User-selectable stereo/mono modes * Track Controls: control Play/Pause/Forward/Backward using iTrip"s buttons * iTrip Controller App for iPhone and iPod touch (a free download)
