iTrip Controller App
iTrip Controller makes current models of the world's most popular FM transmitter even easier to use with the Multi-Touch display of your iPhone or iPod touch.
Plug the iTrip FM transmitter into your iPod touch or iPhone. Launch the iTrip Controller app and use your Multi-Touch display to tune, scan for clear frequencies and display the frequency iTrip is currently using to play your music wirelessly on your FM stereo. SmartScan one-touch setup finds the best frequency with a tap of the screen. Or you can use iTrip Controller's big friendly knob to tune in by hand. iTrip gives you three user-programmable presets so you can save and quickly recall clear frequencies to transmit on.
