Automatic update
About twice a year, Sirius carries out an update
of the names and positions of the channels. The
update occurs automatically and can take sev-
eral minutes.
Notes
> Under some circumstances, reception may
not be possible, e.g. under certain environ-
mental or topographical conditions. The
satellite radio has no influence on this.
> The signal may not be available in tunnels or
underground garages or near trees, moun-
tains, or other powerful sources of radio
interference.
