How do I activate a SiriusXM trial in a vehicle?

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 refresh your radio by clicking here. You will need your Radio ID in order to send a refresh 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 refresh your radio by clicking here. You will need your Radio ID in order to send a refresh signal.

If you purchased a vehicle and received no information about a trial
If your satellite radio isn't on, you can try refreshing the signal by clicking here (you will need your Radio ID in order to send a refresh signal). If that doesn't work, you can start a new trial by clicking here.
