XM1, XM2 Bands

[passerby]

I am going to answer myself. I finally got it to work. The problem is that the PIE GM12 needs to be booted with the radio. Just a simple battery disconnect for a couple of minutes and, when reconnected, the radio found FM1, FM2, XM1 (XM Radio), XM2 (12 disc CD Changer) and AM.

Everything good to go.

Hope someone finds this useful.
