My '06 has NAV, and the upper display on the dash that shows the Temp/Radio/Time always shows the channel (XM1 150) or something like that, even if I switch mode to Catagory. Shouldn't it display XM Comedy or something? It flashes it briefly, but always goes back to the channel.

I can see all the info on the NAV screen if displaying Audio, but I sometimes have the map on, and it would be nice to see the song, artist, or category on the upper display.

Have I missed something here?
