The 5th generation iPod nano has a radio built in. From the main menu, you can choose Radio and it's pretty obvious how to use it from there. If your radio is not working or not available on your iPod nano, it's most likely because you don't have the headphones plugged in. The iPod nano uses the wires in the headphones as the antenna for the radio. So if the head phones are not plugged in, the radio will not be available
