How to Tune Into XM Channel 0by Stephen LilleyUpdated July 21, 2017
Channel 0 on an XM Satellite Radio receiver doesn't actually contain any programming. Instead, channel 0 displays the identification number for your XM unit on its built-in screen. You may need this number if you're renewing your subscription, starting a new subscription or calling customer service for any reason. Tune to channel 0 in a very specific way.
Press "Power" to turn on your XM satellite radio receiver. After a second, the station the receiver is currently tuned to will display onscreen.
Use the circular tuning dial or the "Previous" button (whichever application applies to your specific receiver) to tune backwards until the station indicator onscreen reads "0."
Wait a few seconds for your tuning selection to register. Your XM radio will scroll your unit's ID number across the screen.
