The Quickseek FM Transmitter from Kensington is a rather convenient device for the iPod. It works converse from most transmitting devices and scans for open airwaves rather than searching through stations till a clear channel is found. Its detachable car charger is very convenient for listening to the iPod in the car. The ClearFM technology reduces noise and enhances audio quality. It also charges the iPod while it plays through your car stereo. It features 3 programmable pre-set buttons and the bright display let you store available FM stations quickly and easily. The designing of the device ensures that it fits snugly despite the iPod covered in a protective gear.

Kensington Quickseek FM Transmitter is for $90.
