Ever heard a song on the radio and don't know what it's called. All the new car radios and hi fi systems should come with a LCD display capable of picking up a text signal, displaying the current song playing, or what this current segment title is, they could even have advertising, or upcoming events etc. Obviously the radio station would be in charge of what is being displayed. I believe though displaying the song title would be the most useful use, for it will increase the music...
