This is why the services need 1 website. I could easily find Sirius' schedule at their website, but I don't have Sirius. I have XM....and I've looked up and down XM's website and can't find anything in regards to the bowl games. I came across some pages from past years, but nothing for this year. I'm assuming XM's doing them as well, but don't know where!
Here is the schedule showing both SIRIUS and XM channels.
