Hi Brian,
It occurred to me that maybe Jolida might have turned the display function off, to get rid of the unit displaying the things you didn't want it to display,( Cinema DSP and Surround mode) so that in my incarnation, nothing displays, other than "stereo", and the station numbers, but not the call letters.
I'll ask Mike when he gets back to me, or I'll call him back after Christmas if he doesn't call me back.
David
