We've completely rethought how the product interfaces with the user both aesthetically and functionally. iTrip now uses the iPod's high resolution LCD for optimal viewing of station information. Additionally the sled design and minimalist controls make this the thinnest FM transmitter for the slimmest iPod to date. Griffin's SmartDisplay™ technology seamlessly integrates all functions and features with the iPod nano. iTrip information is displayed on the best screen in the industry: the gorgeous iPod nano screen. One touch navigation puts all iTrip functions at your fingertip. This also makes iTrip for iPod nano the easiest-to-operate FM transmitter, ever. The exclusive SmartSound™ volume control, dynamically adjusts iPod's volume level for optimal audio quality. Additionally, users can control iTrip's volume level through the iPod's click wheel. iPod nano slides into iTrip and securely connects via the iPod's dock and headphone connectors. iTrip accomplishes all this without adding bulk to the slim, sexy iPod nano. To stay securely attached it uses patented micro grip technology. This technology uses microscopic material to provide a secure grip without ever losing its holding properties. iTrip's innovative selectable mono or stereo modes allow the user to adjust for the absolute best possible reception under real-world conditions. Enable the Mono mode in tough situations, such as large cities with stations crowding the dial for unparalleled reception. Switch to stereo mode for the best audio reproduction when you have a clear station. Keeping your music broadcasting is no problem. iTrip draws its nominal power directly from iPod nano, requiring no batteries or AC adapters.
