Does returning a radio purchased with subscription cancel my SiriusXM subscription?
Does returning a radio purchased with subscription cancel my SiriusXM subscription?

No. If you purchased a subscription with your radio or if you activated your radio you must also cancel your subscription plan. Returning your radio does not cancel your subscription. Some subscription plans are non-refundable or may carry early termination fees. Please check the terms and conditions of your offer carefully before calling for a return.
