Sirius radio not updating channels
Have you already activated your radio, but now you only see the "Preview" channel? Make sure the Sirius XM antenna is in a southern-facing window.
Move the antenna around to see if the signal strength improves.
This update will take approximately 50 minutes to complete, but only requires periodic monitoring, leaving you free to do other things during the process.
It is quick and easy, just give us a call at 1-888-964-2874. This means that the Sirius XM receiver is not getting a signal.
At the programming level, both services now carry essentially the same channels.
Since the merger, the programming on both XM and Sirius has vastly degraded.
There are two stages to this update, the 'Application Software' update and the 'Baseband Firmware' update.
If the antenna is mounted outside, try re-aiming it.
If re-aligning the antenna does not work, try unplugging everything and let it sit for a few minutes, then plug it back in.
This means that the Sirius XM unit cannot detect the antenna.
Make sure the Sirius XM antenna cable is firmly and securely plugged into the cradle.
