Are you using the info mode called "INFO: LINE" when you listen to the radio?

I'm not certain what "INFO: LINE" looks like. I never chose a display mode for radio and for mp3 it's always set to TRACK display.
I can't get to the car ATM, so, from memory: It's a static display (apart from the station's scrolling promotional text) roughly as follows:

[AF / TA / TP indicators]
[Preset #] [Station Name]
[antenna symbol] [Signal Strength] [RDS indicator] [time?]
[Scrolling station promotional text (updated over-air)]

Does that answer your question?
