One of my friends has got an FM Transmitter for his iPod. It simply plugs into the iPod’s earphone socket and transmits what ever is playing to a set FM station meaning you can easily listen to what’s playing on your iPod on your car stereo wire free.

The GT Cube is the same sort of thing but in a much smaller box. It incorporates a microphone so can also be used as a hands free kit in your car. It does look a cool and useful gadget but only if you’re Korean
