The XM Audio page is available in both Marine Mode and
Automotive Mode. The XM tab appears on the Main Menu, even if
the XM Audio Page is turned off.
The XM Audio Page is divided into three panes. The rst pane
contains a list of XM Radio categories into which XM Radio
channels are grouped (Classical, Decades, Trafc, and so on). For
a complete list of available categories and channels, visit the XM
Radio web site at www.xmradio.com. Select All Channels to view
a list of all channels in numerical order. You can also view a list of
your favorite channels.
The second pane shows a list of channels in the selected category.
Each channel has a description and the artist currently playing. You
can adjust this setting to show the song title instead of the artist.
The third pane shows the song and artist or program name, the
channel number and name, and the strength of the XM Radio signal.
