I'm having a similar problem getting SiriusXM Online working with a 2 series processor.
I have entered the username and password in the Web GUI for the NSP however I can see in Simpl Debugger that when I select SiriusXM as a source it is prompting for it again. Nearest I can tell there is no way to enter this without Smart Graphics and a 3 Series Processor. I have tried sending it through the keyboard txt input however it appears to do nothing and no response is received from the keyboard txt feedback either.
Any suggestions?
