Do you have level II or above with the nav screen? If level I, audio-comfort, it doesn't have built in satellite radio. That's what my 2010 is, the base level I, and I have an add on Sirius radio plugged into the AUX cable in the left pocket.
If you have a Sirius/XM unit it should work on channel 1. It is an info channel about Sirius/XM But it is a good test to be sure you have the capability and connection necessary to use it. While on Channel 1 it may show your radio serial number or you may need to press a button or two to find it. Contact Sirius/XM with that serial number to get it turned on.
