I called to bitch at a favorite radio station because I never know which artist, which album, which song, etc. unless they explicitly say something on-air. Even their website, which will play their broadcast, doesn't tell you what they're playing at the time.
They say if you have a new radio in the car alot of them have the information that will come on the display while the song plays.
What's this technology called and how can I get that broadcasted info recorded or seen if my new HU doesn't have that feature?
