If the Jensen you have has bluetooth you can always install the SiriusXM app and stream the channels (if you already have a SXM subscription, and if you have cell signal available where you travel).
I believe the SXM receiver you have to plug in is kind of hard to find (may have to get it from Jensen).
Jensen does have a PDF that describes what "Sirius Ready" means:
