Hello everyone. I am a Jag noob. I purchased a 2013 XJ with a Sirius radio in it. The problem is that the radio is incapable of picking up many XM stations even though they merged. I have called Sirius XM and they said I have to have the dealer add an XM module. I called the dealer and they said they don't do that. Has anyone added XM to their Sirius radio in their XJ. IF so any help would be appreciated. I am in the US
