Crutchfield offers the SiriusXM SXV300V1 Satellite Radio Tuner for $69.99. Activate your radio and redeem this $70 mail-in rebate to make it $0. With free shipping, that's tied with our Cyber Monday mention and the lowest total price we could find by $35. This tuner plugs into your pre-existing SiriusXM-ready car stereo and features a hideaway tuner and magnetic antenna. Rebate expires December 31, 2017.

Note: You must choose a Select or greater subscription when activating your radio and maintain 60 days of continuous paid service before your rebate will be processed.
