UPDATE: Dealer took the Tech II and "relearned" the info to the head unit. now it works. At first he tried blaming the use of the Sirius Antenna we isntalled and I said than why is there no XM option? If it were an antenna issues, it just wouldn't have come in, but not deleted the XM option.

so they ordered up a new XM receiver.

Since they "relearned" (I'm not sure wth that really means) I now have XM again without reception issues at all.

So some way, some how, (from the info I got from the dealer) the head unit lost info that it had an XM receiver to talk with

OR

did the XM receiver stop transmitting to the head unit.

I'm still confused as to waht really happened, but I do know I am getting anew receiver.
