Xm Radio: How Do I Find My Radio Id?

[Argelius]

My trial period for XM has expired and I need my radio ID to sign up for the service. I understand that I am supposed to tune to Channel 000 to get this information. However, I can't get the radio to tune to that channel -- if I go to Channel 001 and go back one, it jumps past 000 to the next channel (like 999 or whatever it is). Any ideas?

Thanks.

(PS Have a 2007 GSh)

Well, figured it out. Still couldn't get 000 to tune. Scanned other channels and found 255 which (very discretely and in tiny print at the top of the screen) showed my radio ID...
