Radio Question
 

I have the SiriusXM-capable 6-disc changer radio. My wife has an '09 Cadillac SRX with basically the same radio, only with an LCD screen instead of the LED.

On her radio, the display scrolls--channel name, song name, artist name, rinse and repeat. On mine, it will scroll for terrestrial radio, but when it's on SiriusXM, it stays on whatever I choose with the "i" button and will not scroll.

SiriusXM swears it's an issue with the radio. I swear that if it were the radio, it would act the same on all bands.

Who's right? And if it's me, how do I fix this problem? It doesn't make sense to me that in a car with so many features designed to keep my eyes on the road, I should have to punch buttons to find out who's singing the cover of "Wichita Lineman."
