XtremeMac have released a handy device called "AirPlay" that lets you listen to music stored on your iPod via any FM radio. The device, which also works with the iPod Mini, transfers audio wirelessly from the music player to any FM radio with ease, and even tells you the frequency you'll be transmitting on. Smart with iPod battery life and able to automatically transmit on the last used radio frequency, AirPlay is the only transmitter that will work with any FM radio and iPod, despite an increasing number of new gadgets for the iPod.
