Griffin Technology iTrip

If you're still using a clunky cassette-style adapter to connect your iPod to the car stereo, consider cutting the wires with Griffin's iTrip FM transmitter. The iTrip lets you transmit music from the iPod directly to the car's FM tuner. While the sound quality through any portable FM transmitter is less than perfect, the iTrip sounds decent, though some interference is noticeable at times. These units let you choose the broadcasting frequency from the iPod's elegant interface, unlike others that offer a sparser range of frequencies that must be selected via a tiny switch.
