Why doesn't the Zune show song info when listening to the radio for every station?

Question

This doesn't work for some stations, and it's the ones that are not-for-profit stations. Could this be because the station doesn't have the right equipment? What does the station need to have in order for a Zune to pick up the song info?

Answer 1

[4] To display station name and song information, stations must broadcast an RBDS signal. Availability may vary so check out your favorite stations on your Zune to see if this functionality is present.

Basically radio stations that want to, send out a text signal if you will of what they want to have displayed. sometimes it's the name of the station, most big cities, the stations will provide artist and song info.

But depends on the station and it's mostly major stations doing this only currently.
