iTrip DualConnect combines Griffin's renowned FM transmitter technology with a plug for your car's 12 volt power outlet. An integrated cable plugs into the dock connector of your iPhone or iPod touch so iTrip can charge its battery while you drive. Control iTrip and perform the quick and easy setup using the free iTrip Controller App. Setup is a snap: just press the SmartScan button on your Multi-Touch display, then tune your car radio to the frequency that SmartScan finds for you. It's that simple. iTrip features put the customer first. User-selectable stereo and mono modes; programmable presets so you can save the most useful FM frequencies for quick recall. And Griffin SmartSound technology optimizes the signal for best sound. For car stereos that feature an auxiliary audio port, iTrip DualConnect provides an AUX jack. So you can use iTrip's FM transmitter to send the music wirelessly to your car radio, or connect your iPhone or iPod touch through iTrip directly to your car stereo. Either way, illuminated buttons on iTrip's charger plug give you Play, Pause, Forward and Backward track controls that you can operate by touch while driving.
