Sorry, but that's not correct. Turning XM Weather on/off and using XM Radio
just happen to appear on the same page in the Quick Ref, but there is no
correlation between the two.

Obviously, you will need to leave the Map Page where the weather data is
displayed in order to go to the XM Audio Page. The XM Audio page is where
you select your channels, and it also has a Mute/Enable audio output
selection, which determines whether the radio is heard.

Once you have tuned the XM radio and Enabled audio output, the radio will
continue to play even if you leave the XM Audio page and return to the Map
Page to view the weather...

Thanks for the correction... And at the bottom of the page it mentions
seperate subscriptions for Music and Weather...

The PDF for the GXM30 antenna shows some additional screen shots...
