The Incharge FM from XtremeMac is a stylish FM transmitter that features Quintic's PureFM technology along with proprietary audio enhancements. Connect your 4th generation or later docking iPod and plug the transmitter into your car's 12VDC accessory outlet. Once you're tuned to the best station, enjoy listening to your music on a clean and consistent FM signal in stereo or mono modes. For future reference you can save the two best signals to the programmable presets for quick retrieval at any time. The Incharge FM also features an easy to read LED screen and play, pause, and next track functions. While your iPod is connected it also charges up to 2x faster than with a standard computer.
