Some common problems that can occur with Sirius radio include poor reception, failure of the unit to power on, and the screen continuously flashing "Acquiring Signal" without ever acquiring it. Some of these problems can be resolved by troubleshooting, but more often than not, new equipment is required.
One common problem users have with Sirius satellite radio is that the system is not always able to detect the antenna. When this happens, the unit alerts the user by reading "Antenna Not Detected," "No Antenna" or "Check Antenna." If a Sirius screen flashes one of these three messages, it is an indicator that there is something wrong with the antenna. It could be that the antenna wire has a kink in it, that the magnetic base of the antenna has somehow gotten wet or damaged, or the unit is just too old to work properly. If any one of these scenarios occurs, the best way to resolve the problem is to purchase a new antenna.
Another common problem with Sirius radio is audio fading or static interference during use. When this happens, Sirius recommends users check to ensure proper connection of all cables. Interference from another channel often causes this problem.
