I have an N-3, running the n-4 map disks. What is the difference in display from the crappy sirius display to the XM dispay. My wife just got a GM car with XM and am considering switching mine to XM, but only if the display is full, i.e. all the info, artist, title etc. Related, does the display change with the Nav capable XM tuner vs. the audio only tuner?? Help is appreciated! I apologize if this has been answered in the past, I searched and could not find an answer relating to this. Brett
