Sirius radio
 

So I bought a 2013 left over Z and never thought to check if I could get the free months of Sirius as I don't like it. Now I find it annoying to switch from Bluetooth to Cd to FM and having to hit at least 3 channels of Sirius radio in the process. I use the button on the steering wheel to do so. On that note I wonder if there is a way to skip these setting and just have my 3 favorite options available, BTW the button I use is the 'Source" button.
Thanks in advance
