To display METARs on the XM Weather page:
1.
While viewing the XM Weather page, check
the upper left corner to see whether "METAR"
or another weather product is displayed in the
upper left corner.
2.
If another weather product (rather than
"METAR") is shown, press the small right

such as "NEXRAD". Turn the small right knob
to change to "METAR," and press that small
right knob again to bring down the cursor
(stop the highlighting) and retain the "METAR"
selection.
3.
Now, colored flags will be displayed at those
airports that have METARs above a certain
severity level. (If there are no colored flags
visible, you may have to search a wider
area—zoom out with the RNG key—before
you see some METAR flags.)
To display the METAR Legend:

Press the MENU key to display the Page
Menu.
Turn the large or small right knob to select
