Has anyone replaced the Sirius satellite tuner with a XM tuner? I had an XM tuner in my previous car and now have Sirius in my 2010 Outlander GT. I realized that Sirius doesn't broadcast MLB and NFL play-by-play on the radio (online only) and XM does. I'm totally bummed and want to replace Sirius with XM tuner. Curious if anyone else has done this.
