Thanks for the tip---after much searching I found the dial and am now able to listen to something other than XM kids for the first time in months.
My job entails a lot of time on the phone---much of it on hold. Here in Chicago, the "at work (crap lite)" station switched to x-mas music about November 2. Guess what everyone has piped on their hold system? If you were forced through the pain of Bob Seger's "Little Drummer Boy" three or four times a day (as well as about 10 versions of the Christmas song) four WEEKS before Christmas, you might understand my reticence on cranking my X-Mas XM music.
