Frequently Asked Questions - SXMTTR3 SiriusXM
How do I activate my SiriusXM SXMTTR3 radio?
Turn on the radio and tune to channel 0 to get your Radio ID. Visit SiriusXM.com/activate or call 1-866-635-2349. Have your Radio ID and payment info ready.
Can I use the SXMTTR3 without a subscription?
No, the SXMTTR3 requires an active SiriusXM subscription to receive any audio signal. Without one, only the FM transmitter and menu functions work.
How do I set up the FM transmitter?
Go to Menu > FM Settings. Choose an unused FM frequency (e.g., 88.1). Tune your car radio to the same frequency. Adjust volume on both devices.
Why is there no sound from the speakers?
First, ensure the radio is powered on. Check that the FM transmitter or AUX cable is properly connected. Verify the car radio is on the correct FM frequency. Also confirm your subscription is active.
How do I update the software on my SXMTTR3?
Updates are delivered via satellite. Keep the radio powered on and tuned to channel 0 for at least 30 minutes. The update will install automatically. Do not turn off the device during this time.
Can I use the radio indoors or in other countries?
The SXMTTR3 is designed for use in the United States and Canada only, as SiriusXM satellite coverage is limited to these regions. Indoor use requires a clear view of the southern sky via a window.
What does the 'No Signal' message mean?
This indicates the radio cannot detect the SiriusXM satellite signal. Check that the magnetic antenna is properly mounted on the roof or trunk of the car with a clear, unobstructed view of the sky. Also ensure the cable is fully inserted.
How do I reset the SXMTTR3 to factory settings?
Press and hold the Menu and Power buttons simultaneously for 10 seconds. Release when the screen flashes. This will erase all presets and settings.
Is the SXMTTR3 compatible with SiriusXM All Access subscription?
Yes, it supports All Access, which includes all channels, on-demand, and streaming. However, streaming features require the SiriusXM app on a phone and a Bluetooth connection.
How do I clean and maintain my SiriusXM radio?
Use a soft, slightly damp (not wet) microfiber cloth to wipe the exterior. Do not use chemical cleaners. For the screen, use a dry cloth. Remove from high-heat environments. Store in a cool, dry place.
