TSSRadio SXV300 SiriusXM Tuner Module

The TSSRadio SXV300 is a dedicated SiriusXM tuner module that adds satellite radio reception to SiriusXM‑compatible aftermarket headunits when paired with a satellite antenna.

If your car stereo is labeled "SiriusXM Ready" but lacks an internal tuner, the SXV300 provides the hardware needed to receive SiriusXM channels. This tuner itself does not include an antenna — you must connect either a factory satellite antenna or a compatible antenna adapter to pick up satellite signals. The SXV300 is designed to retrofit cleanly into many aftermarket systems that support SiriusXM external tuners.

How does the SXV300 integrate with my existing headunit?

The SXV300 uses the headunit's SiriusXM tuner input so the radio can control channels and display metadata. Installation typically involves connecting the module to the headunit's satellite input and routing the antenna cable into the vehicle.

• Plugs into aftermarket "SiriusXM Ready" headunits via standard tuner input
• Uses the headunit interface for channel selection and display
• Requires a free tuner port on the stereo or an available harness
• Works with factory or aftermarket satellite antenna via adapter

What antenna or adapter do I need to use the tuner?

The SXV300 cannot receive satellite signals without a compatible antenna. If your vehicle already has a factory satellite antenna, an adapter may not be necessary; otherwise, choose an approved satellite antenna or a harness adapter that matches your car's connector.

• Compatible with factory satellite antennas when connectors match
• Aftermarket satellite antennas are supported when rated for SiriusXM
• Antenna adapters are available for nonstandard factory connectors
• Proper antenna placement and routing improve reception quality

Will this tuner work with my vehicle and stereo brand?

The SXV300 is intended for use with aftermarket headunits that explicitly support an external SiriusXM tuner. Verify that your stereo is listed as "SiriusXM Ready" and that it has the appropriate tuner input before purchasing.

• Compatible with many aftermarket headunits labeled "SiriusXM Ready"
• Check your headunit manual or manufacturer compatibility list first
• May require a vehicle‑specific harness or mounting bracket for neat installation
• Not a standalone radio — needs an existing SiriusXM‑ready headunit

How do I activate and set up satellite service after installation?

Once the SXV300 is connected and the antenna is functional, power up the headunit and follow SiriusXM's activation steps. Activation typically includes tuning to the correct activation channel and registering the radio ID with SiriusXM.

• Tune the headunit to the SiriusXM activation channel displayed in the manual
• Provide the radio or tuner ID to SiriusXM for service registration
• Activation can be done online or by calling SiriusXM customer support
• Signal strength and channel availability depend on antenna placement

Who is this for: The TSSRadio SXV300 suits drivers who already own an aftermarket headunit marked as "SiriusXM Ready" and want to add satellite radio without replacing the entire stereo. It's a practical choice for installers, car audio enthusiasts, and vehicle owners with a compatible factory antenna or those willing to install a proper satellite antenna or adapter. If you need an all‑in‑one radio or a unit lacking a tuner input, consider an alternative solution that bundles tuner and headunit together.
