Do I need to upgrade software on non-mobile devices in order to listen to SiriusXM Internet Radio?
No, you do not need to update software for non-mobile devices like the SiriusXM Media Player or TTR1 in order to listen to SiriusXM Internet Radio on these devices. However, if you listen to SiriusXM Internet Radio via a mobile application, you will need to update the application to continue listening on your mobile device.
