What does tuner error mean on Sirius Radio?

Tuner error on Sirius radio means that there is a conflict with the channels initializing. This usually happens when there is a tremendous amount of static or electronic interference in the area. The problem, however, can also stem from the transmitter not being able to connect with wireless, car, or stationary radiOS. This issue usually resolves itself within a little while, and allows users to access all their favorite channels again.
