The piece is also quite easy to use. It plugs into the iPod's universal connector doo-dad at the bottom and works from the second it's attached. Only a few buttons are present on the unit; one controls its transmitter role (in, out, off). A set of four buttons act as presets for those who are too lazy to tune the device themselves using the "+" and "-" buttons. Unfortunately, in order to listen to the radio, the headphones must be switched into the jack on the Transmitter itself. Not the biggest deal in the world, by any means, though.
