If your SiriusXM radio is showing channel names but playing silence, skipping channels, or displaying a “Subscription Updated” message that never clears, a signal refresh is usually the fastest fix. A refresh sends an activation update from the satellite network to your specific radio so it recognizes your current subscription status.

​
When to send a refresh signal

A refresh is helpful when:
  • You recently activated or renewed a subscription and channels are still not working after 15 minutes.
  • Your radio shows “Subscription Updated” or “Call SiriusXM to Subscribe” on every channel.
  • Some channels work while others do not, even though they are part of your plan.
  • You moved your radio to a new vehicle and need to reactivate it.
If your radio shows “Check Antenna” or “No Signal,” a refresh alone may not fix the issue. See the troubleshooting guide first.

​
How to refresh your signal

1

Turn your radio on

Start your vehicle or power on your standalone radio. Make sure it is tuned to SiriusXM channel 1 or the preview channel, not an FM station.
2

Move outdoors if possible

Park in an open area with a clear view of the sky. Garages, parking structures, and dense tree cover can block the satellite signal while the refresh is being sent.
3

Request the refresh

Visit the official SiriusXM website or use their mobile app to send a refresh signal to your radio. You will need your Radio ID (also called ESN or SID). If you do not know it, see how to find your Radio ID.
4

Wait several minutes

Leave the radio on and tuned to channel 1. The refresh can take up to 5 minutes to arrive. You may hear a brief tone or see the channel list update when it completes.
5

Test your channels

Once the refresh is done, tune to a few different channels to confirm audio is playing. If channels are still silent, try turning the radio off and back on.
You can typically send one or two refresh signals per day through the official site. If you need more, contact SiriusXM customer care directly.

​
What to do if the refresh does not work

If you have waited more than 10 minutes in an open area and your radio still is not working:
  • Double-check that your subscription is active by logging into your account on siriusxm.com.
  • Verify you entered the correct Radio ID when requesting the refresh.
  • Try moving to a different location with a clearer view of the sky.
  • Power cycle the radio by turning it fully off, waiting 30 seconds, and turning it back on.
If none of these steps help, contact SiriusXM customer care for further assistance.

Find Your Radio ID

Locate your ESN or SID on channel 0 or on a label on the radio unit.
