SiriusXM has 2 (operational) geosynchronous satellites positioned parallel and literally over and on either side of TX (longitudes of 96 & 115 W). Most of the CONUS is "north" of that so people would usually "point south" although the better way to describe it is to point towards TX. However they also have a bunch of terrestrial repeaters on the ground to boost the signal and that can help - at least in urban areas where it can be harder to get line-of-sight.

Some of the speaker docks (and I have had a few different ones over the years) are kludgy for volume controls and also tend to have options for an "aux" input where if that is selected (or something is plugged into that jack), it is assuming some other external device is going to use the speakers and not the receiver itself.
