## General questions

<AccordionGroup>
  <Accordion title="How do I activate my XM radio?">
    Find your Radio ID on channel 0, enter it on the official SiriusXM website or app, choose a plan, and keep the radio on until channels unlock. Full guide: [XM radio activation](/blog/xm-radio-activation).
  </Accordion>

  <Accordion title="Is XM radio the same as SiriusXM?">
    Yes, today they are one service. XM and Sirius merged in 2008 to form SiriusXM. Read [XM radio vs SiriusXM](/blog/xm-radio-vs-siriusxm).
  </Accordion>

  <Accordion title="Where is my SiriusXM Radio ID?">
    Tune to channel 0 or check your radio settings or the label on the device. See [Find your Radio ID](/blog/find-radio-id).
  </Accordion>

  <Accordion title="How long does SiriusXM activation take?">
    Usually a few minutes, but it can take longer. Keep the radio on with a clear view of the sky the whole time.
  </Accordion>

  <Accordion title="Why are my channels still locked after activation?">
    The radio has not received the signal yet. [Send a refresh signal](/blog/refresh-siriusxm-radio) while parked outside.
  </Accordion>

  <Accordion title="What is SiriusXM with 360L?">
    It is a newer in-car platform that combines live satellite channels with on-demand content and personalized recommendations. Some features need the vehicle's data connection.
  </Accordion>
</AccordionGroup>

## Trials and subscriptions

<AccordionGroup>
  <Accordion title="Does my new car come with a free SiriusXM trial?">
    Many new and eligible pre-owned vehicles include a SiriusXM trial subscription. Almost all new vehicles arrive factory-activated. Check with your dealer or on the official SiriusXM website using your VIN. Full details: [SiriusXM Free Trial](/blog/siriusxm-free-trial).
  </Accordion>

  <Accordion title="How do I start streaming on the SiriusXM app?">
    Many plans include app streaming. Get your login at siriusxm.com/getlogin and download the SiriusXM app on your phone or tablet.
  </Accordion>

  <Accordion title="Can I activate an old XM radio?">
    Many older radios still work, but some very old models are no longer supported. Enter the Radio ID on the official site to check eligibility.
  </Accordion>

  <Accordion title="What happens when my free trial ends?">
    Your trial will automatically transition to a paid subscription unless you cancel. Check the official SiriusXM website for renewal terms and cancellation options.
  </Accordion>
</AccordionGroup>

## Buying, selling, and transferring

<AccordionGroup>
  <Accordion title="I bought a used car. How do I get SiriusXM?">
    Activate the radio under your own account on the official SiriusXM website. This links the radio to you instead of the previous owner. You may need the Radio ID rather than the VIN if the head unit was replaced. See [Transfer SiriusXM to a new car](/blog/transfer-siriusxm).
  </Accordion>

  <Accordion title="How do I transfer SiriusXM to a new vehicle?">
    Existing subscribers can move service, add a vehicle, or deactivate an old one at siriusxm.com/transfer. Have both old and new Radio IDs ready. Full guide: [Transfer SiriusXM to a new car](/blog/transfer-siriusxm).
  </Accordion>

  <Accordion title="I am selling my car. Should I deactivate SiriusXM?">
    Yes, if you no longer own the vehicle. Use siriusxm.com/transfer to deactivate the old radio so you are not charged for a car you no longer have.
  </Accordion>
</AccordionGroup>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Why does my radio say No Signal?">
    The antenna cannot see the sky or the cable is loose. See [SiriusXM not working](/blog/siriusxm-not-working).
  </Accordion>

  <Accordion title="What does Check Antenna mean?">
    The antenna or its cable may be disconnected or damaged. Reconnect it. If the message stays, contact a car audio installer or dealer.
  </Accordion>

  <Accordion title="Is it safe to activate SiriusXM on third-party websites?">
    No. Only use the official SiriusXM website, app, or customer care. Third-party activation sites may charge hidden fees or steal card details.
  </Accordion>

  <Accordion title="Can I listen to SiriusXM without a satellite radio?">
    Yes. The SiriusXM app streams on phones, computers, and smart speakers. Streaming access depends on your plan.
  </Accordion>

  <Accordion title="Why does my SiriusXM cut out while driving?">
    Brief dropouts near bridges, tunnels, and dense city streets are normal. Constant dropouts may mean a weak antenna connection.
  </Accordion>
