Step 1
Try refreshing the activation of your radio by going to the XM or Sirrius websites and hitting "refresh signal."
-
Step 2
Check with customer service to make sure the radio has been properly activated. Sometimes the request doesn't get processed right away.
-
Step 3
Check your antenna. Make sure it's connected to the proper input on the radio and can get a clear signal. Also check the cable and connector for damage. Your radio won't receive a signal if you're in a garage or other area where the signal is blocked.
-
Step 4
Set your radio, in most cases to Channel 1, so it can acquire the stations from the satellite. Then switch to several other channels to test it.
-
Step 1
Check to see if there's fringe interference from a nearby radio station. In this case, you'll hear either static from the station or voices and music will be heard faintly in the background. Many satellite radios are equipped with RF modulators, which use FM frequencies to deliver sound through your car's speakers.
-
Step 2
Test the radio with several unused FM frequencies to find the clearest channel. If you get a weak signal and you're sure there's no interference, try relocating the antenna.
-
Step 3
Use the car's cassette player to connect to your sound system. Unfortunately not all brands of satellite radio come with a cassette adapter, but they're pretty easy to get. Just plug it into the audio out jack of your radio and pop the end with the cassette into the player.
-
Step 4
Test your receiver with a home kit. If all of your stations come through loud and clear, there could be a problem with the RF modulator. In that case exchange the radio for a new one.
-
Step 1
Check to see if your radio is locked. This may be the case if you can't change stations and a "lock" signal is displayed on the radio. You can turn this off on some radios by pressing the "Mute/Pause/Lock" button. If your radio doesn't have this, or it doesn't solve the problem, unlock it by inserting the end of a paper clip into the radio's reset hole.
-
Step 2
Reset the radio by inserting the end of a paper clip into the radio's reset hole to alleviate problems if the back light of the radio doesn't turn off or on or the radio's display doesn't change.
-
Step 3
Check your radio's battery to make sure it's fully charged.
-
Step 4
Do not tune a channel that's been blocked. If that's the case, and you now want to receive the channel, you'll have to call either XM or Sirrius customer service.
