Authorizing XM Radio Issues

Wednesday I started the car to drive to work and switched from BlueTooth (which I was listening to all day Tuesday) to Satellite and the XM channel switched to 001. I attempted to switch to other channels but received an UNAUTH. I immediately pulled over and called support and had a radio signal sent (it was 5:00AM so I did everything over the phone). It didn't work. Got to work and logged in and had a radio signal sent. Same result - it didn't work.

My account is paid up through 2014. Satellite radio has been solid since I bought the vehicle 1.5 years ago.

I called support and they resent the signal. Didn't work. They had me open the door for 2 minutes with the car off and resent the signal. Didn't work. They recommended I go see my dealer.

On the way home I noticed NavTraffic WAS working. I contacted support again and let them know about NavTraffic, and after putting me on hold for 10 minutes, verified my account was in good standing. After a few attempts at resending the signal again, satellite radio still doesn't work. They recommended I take the car back to the dealer.

I made an appointment for Monday with the dealer but was checking to see if anybody had ideas. Is there a XM satellite reset for the Prius? Bad antennae? Bad radio?

Thanks for your help.
