Quick Take: Here's an FM-transmitting car kit for the iPod Shuffle that gets it right. About a foot long, the $45 iTube-101 is a stiff but flexible rod with a cigarette-lighter adapter at one end, an FM transmitter/controller in the middle, and a Shuffle port on the opposite side. The controller has an LCD readout and a trio of buttons that lets you change the FM frequency. The rod is also flexible enough to shape to your liking without flopping between the seats while you're on the road.
