## Common problems and fixes

<AccordionGroup>
  <Accordion title="No Signal or Acquiring Signal">
    The antenna cannot see the sky. Drive into an open area away from tunnels, bridges, covered parking, mountains, tall buildings, and heavy foliage. For home radios, move the antenna near a window with a clear view of the sky. Check that the antenna cable is firmly connected.
  </Accordion>

  <Accordion title="Check Antenna or Antenna Error">
    The antenna or its cable may be loose or damaged. Reconnect the antenna securely. If the message stays after checking connections, the antenna may need to be replaced by a car audio installer or dealer.
  </Accordion>

  <Accordion title="Channels locked after activation">
    The radio has not received your subscription authorization yet. Keep it on, park outside, and [send a refresh signal](/blog/refresh-siriusxm-radio) from the official SiriusXM website.
  </Accordion>

  <Accordion title="Subscription not found or Call to subscribe">
    The Radio ID may be typed wrong on your account, or the subscription expired. Recheck your [Radio ID](/blog/find-radio-id) and your account status on the official SiriusXM site.
  </Accordion>

  <Accordion title="Updating Channels or Updating SiriusXM">
    This means SiriusXM is updating the channel lineup. Channels may be added or removed. Wait for the update to finish. If it takes a long time, try turning the radio off and on again while outside.
  </Accordion>

  <Accordion title="Preparing SiriusXM Radio stuck">
    If the message stays on the screen and the radio does not respond, try resetting the head unit. The method varies by car; common ways include holding the power button for 10 seconds or disconnecting the car battery for a few minutes. If the problem persists, contact your dealer.
  </Accordion>

  <Accordion title="Sound cuts out on the road">
    Short dropouts near bridges, tunnels, and dense city streets are normal. Constant dropouts can mean a weak antenna connection or a failing antenna. Check the cable and consider antenna replacement if dropouts happen in open areas.
  </Accordion>

  <Accordion title="Start-up error">
    Try resetting the head unit and sending a refresh signal. If the error continues, the radio may need dealer service or replacement.
  </Accordion>
</AccordionGroup>

## What causes signal loss?

Tunnels, bridges, covered parking, mountains, tall buildings, and heavy foliage can briefly interrupt the satellite signal. This is normal. If you lose signal in wide open areas with no obstructions, the antenna or its connection may be faulty.
