Belkin's TuneCast II Mobile FM Transmitter for iPod gives you the power to transmit your digital music via any FM frequency, so you can listen to your tunes on your car stereo. The TuneCast II is also compatible with many other MP3 players, CD players, laptops or just about any device with a headphone jack. Simply tune your TuneCast II to a seldom-used FM frequency and you'll be ready to jam to your digital music on the road. The stylish TuneCast II allows you to program four stations for best reception in any area as well as an auto on/off switch to conserve battery life. So you don't have to worry about running out of juice, the TuneCast II already comes with a 14-inch cable for connecting to Belkin's Mobile Power Cord for iPod (sold separately).
