A refresh resends your subscription authorization to the radio. Use it when you are subscribed but channels are missing, locked, or display a message like “Call SiriusXM to subscribe.” You can request a refresh from the official SiriusXM website using your Radio ID or VIN.

​
Quick answer: how to refresh

  • Park outside with a clear view of the sky.
  • Turn the radio on and tune to the preview channel (channel 1 on many radios, 184 on some).
  • Visit the official SiriusXM refresh page and enter your Radio ID or VIN.
  • Keep the radio on until a confirmation message appears. The refresh signal is sent twice; the first can arrive in seconds and the second up to about 5 minutes later.

​
When to refresh your radio

  • Right after XM radio activation, if channels do not unlock.
  • After you change or upgrade your plan.
  • After a car battery change, radio repair, or head unit replacement.
  • When channels that were working suddenly show as locked or missing.
  • After transferring service to a new vehicle.

How to send a refresh signal

1

Park outside

Move your car to an open area with a clear view of the sky. Garages, tunnels, and covered parking will block the signal.
2

Turn the radio on

Switch to SiriusXM mode and tune to channel 1 or any preview channel. On some radios, channel 184 is the preview channel.
3

Request the refresh

On the official SiriusXM website, find the refresh radio option at siriusxm.com/refresh and enter your Radio ID or VIN.
4

Keep the radio on

Leave the radio on until your channels return. Do not switch off the car or change the channel during this time.
The refresh signal is sent twice. The first may arrive in seconds, and the second can take up to about 5 minutes. If channels do not return after the second signal, wait a few minutes and try again before contacting customer care.

​
Radio ID vs VIN for refresh

The Radio ID is more reliable than the VIN for refresh if the head unit was replaced. If you recently had a new radio installed, always use the Radio ID from the new unit instead of the VIN.
