SiriusXM SXV300V1 Vehicle Satellite Radio Tuner & External Antenna (Renewed) — SiriusConnect Compatible

The SiriusXM SXV300V1 is a vehicle satellite radio tuner and antenna kit that brings SiriusXM channels to compatible factory or aftermarket radios with a required subscription.

If you want satellite radio in a car that didn’t come with it or want a simple aftermarket add-on, the SXV300V1 provides the tuner hardware and external antenna needed to receive SiriusXM programming. This renewed unit is designed to integrate with many receivers using SiriusConnect interfaces, allowing access to music, talk, sports, and news channels when paired with an active SiriusXM subscription (subscription sold separately).

How does the SXV300V1 connect to my existing car stereo?

The SXV300V1 connects to compatible radios using SiriusConnect wiring and an antenna input. Installation typically requires tapping into the head unit’s auxiliary tuner port or using an interface harness for factory systems. Professional installation or a vehicle-specific wiring guide will simplify the process.

• Uses SiriusConnect-compatible tuner interface for direct integration
• Works with many aftermarket head units and factory radios
• Requires antenna placement with supplied external antenna hardware
• May need an adapter harness for some factory-installed stereos

What performance and reception should I expect on the road?

The external antenna included with the SXV300V1 is tuned for satellite reception to reduce dropouts and improve signal lock in most driving conditions. Reception quality depends on clear sky view and correct antenna placement; urban canyons or heavy tree cover can affect performance.

• External antenna designed for optimized satellite signal capture
• Improved channel stability when antenna is mounted on a clear roof or trunk area
• Typical performance improves with professional mounting and routing
• SiriusXM subscription needed to unlock channels and features

What’s included and what should I check before buying a renewed unit?

The renewed SXV300V1 package generally includes the SiriusXM tuner module and the external antenna assembly. Before purchase, confirm compatibility with your radio and inspect the seller’s renewal condition and warranty terms.

How do I activate and start using SiriusXM with this tuner?

• Install tuner and antenna, power up the head unit
• Locate tuner ID and register/activate at SiriusXM (subscription required)
• Wait for signal lock—antenna placement affects time to activate
• Use radio’s satellite band to browse channels after activation
