Have Infinity "premium" audio sys in 2009 Santa Fe Limited w/XM satellite radio. Really like it -- but want to change the display so that the song title & artist name is the default display. The current default display shows the XM channel number and name (i.e., "Watercolors, XM channel 71"). Anybody know if I can choose and change to the display I want? Have called Infinity Tech Support, but they "don't assist customers with factory-installed Infinity audio systems."
