XM Tuners for OEM or Aftermarket Radios

If you already own a XM-ready headunit or a backwards-compatible factory headunit, you've got a good start towards having XM Radio. All you need is a Digital Satellite XM Tuner, which hides somewhere in your vehicle and delivers a steady stream of the radio you've always wanted, crystal clear no matter where you are. The XM tuner sends display info to your headunit, including channel name and number, artist, song name, and other information.
