Play itunes library to FM

[Macs4u]

Hi,

Recently i saw someone with an ipod and they were playing their itunes library and telling me to tune into 82.2fm and it played through the radio. Is that built in or is it an app?

I think an external FM transmitter is needed for doing this.
such as one of these:
