How do I activate a SiriusXM trial in a vehicle equipped with a SiriusXM, XM, or Sirius satellite radio?

If you purchased a new vehicle with factory-installed SiriusXM

Your trial should be active at the time of purchase. If your radio isn't on or receiving all the appropriate channels, simply send a signal to your radio by clicking here. You will need your Radio ID in order to send a signal.

If you purchased a pre-owned vehicle

If the dealer told you your pre-owned or certified pre-owned vehicle came with a complimentary trial, the trial should be active at the time of purchase. If your radio isn't on or receiving all the appropriate channels, simply send a signal to your radio by clicking here. You will need your Radio ID in order to send a signal.

If you purchased a vehicle and received no information about a trial

If your satellite radio isn't on, you can try sending a signal by clicking here (you will need your Radio ID in order to send a signal). If that doesn't work, you can start a new trial by clicking here.

Please note: When resending a signal, your radio needs to be powered on and tuned to Channel 184 for Sirius radios or Channel 1 for XM and SiriusXM radios. Also, be sure your antenna has a clear view of the sky before resending a signal. To verify your signal, simply tune to Channel 4. If you hear audio, no further steps are required.
