help with xm radio

[firewalkjoe]

I just bought a used 2007 Vibe and can't seem to find the XM radio ID # to activate the service. The radio has 2 XM presets, so I assume it is XM ready, but when I tune my radio to those channels it shows XM Radio 1 (or 2) and then switches to aux. I can't tune to channel 0 to find the ID#. Any help or information would be appreciated.

Thanks!
