Errors are bound to happen. The tech at Stein noticed that the GDL51R, XM receiver, was improperlly mounted to the sub instrument panel. I should have looked a bit closer. So, thanks to Nick's eagle eye, today I fabricated a tray to properly mount this device. I used four of the six nut plates previously installed on the sub panel as mounting points for the tray. This part of the universe is back in alignment.
