After carefully reading the manual for the '09 Azera Limited w/ Infinity PA760S radio, I can't figure out if -- and if so, how -- to get the display to show the call letters of the FM station being played as well as the song titles and artisits as so many radios do. No one at the dealer seems to know.

Also, cannot figure out what the CAT(FLDR) button does. The SET UP button seems to just control Text scrolling -- which I can't seem to figure out what it does -- and the XM radio with only one option.

With XM radio, song titles and artists are displayed.

Any help would be appreciated.
