I discovered SiriusXM notifications while I had a loaner car from the dealer. These pop ups kept coming up telling me there was a Bob Dylan song on another channel. I have other vehicles with SiriusXM and never had seen this before. Doing a little research, I found that my Lightning had this feature as well. I also discovered this feature is called Alerts in Sync 2 and Sync 3. I put together a short video on how to setup notifications on the Lightning. Certainly makes Sirius/XM more useful.
Enjoy!
