Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The radio ID is to be found by tuning to Channel 0. If the buttons that select Channel 0 are disabled when the Sirius tuner is connected, then look for the radio ID on the packaging for the Sirius XM tuner, or on the Sirius XM tuner itself.
You may possibly have no recourse if both the Channel 0 select won't work, and the original ID is gone.
Sometimes used equipment or scavenged equipment (for cars esp.) is like that: of not much usefulness.
But: try switching modes on the radio. Then, for each mode, try once to see if the button for Channel 0 is available and usable. If it *never* ever becomes usable, the radio is trash and should be either repaired or recycled.
