AM-SAT button only gets AM1

This is an odd problem. My radio worked fine until last wednesday, I used SAT radio daily for traffic and weather every morning. Now from one day to the next it doesn't even select SAT when I push the AM-SAT button, it only gets AM1. It doesn't go to any other AM such as AM2 if there is one ( I don't know for sure there is, I never listen to AM, but would like to hear if there is an AM2). My trial subscription wont expire until the 11th and even then I should be able to at least select SAT and hear their promotional channel.

I haven't been fooling with the radio or surrounding dash panels (lately ;P) and I did try pulling and replacing the jumper in the underhood fuse box. That wiped my mileage info but did not restore the SAT radio.

Any ideas?

 

That's how it has worked in other sat radios I've had, plus I received a letter from XM saying it expires on the 11th and it is now the 7th as I write this. Does anyone know if there is actually an AM2? And I pulled the jumper pin to 'reset' the radio,but the presets are still set. I was trying to avoid losing the mileage info but since I already lost that I'm thinking of disconnecting the battery ground and see if that helps. Any other suggestions?

 

Well I called the dealer and they had never heard of this happening to anyone, so they asked me to bring it in. I guess that's what warranties are for, so I'm taking it in tomorrow. I'll post whatever updates after that.

EDIT: The dealer concluded the radio was to blame and has ordered a replacement under warranty. We'll see next week if that takes care of it.
