iTrip Auto is the most advanced iTrip ever

iTrip Auto combines Griffin's renowned FM transmitter technology with an integrated charger that plugs into a car's cigarette-lighter or accessory socket. As with all Griffin products, setup and operation are quick and easy. Press the SmartScan button and tune the car radio to the frequency iTrip chooses for you. It's that simple. (But, of course, you can also select frequencies manually.)

Other features include inline remote controls, assignable presets, stereo and mono play modes, and SmartSound signal adjustment. Add app integration for iPhone and iPod touch with Griffin's iTrip Controller app, a free download from the iTunes App Store.
