The H630SAG000 subwoofer is the rectangular type that I mentioned earlier...

The rectangular sub does not use the satnav's line-level subwoofer output. The on-screen settings do not control that sub directly. You may hear some slight changes, but that would only be due to changes the satnav makes to its main speaker outputs (which is where the rectangular sub gets its inputs).
If you want those onscreen menus to work, you must find a sub that takes a line-level input. There are some recent (2010-2011) rectangular subs for Legacys/Outbacks which do that (in North America, at least). However, their harness may not have wires on all of the pins needed for the satnav we've been talking about in this thread. Probably easier to go with an aftermarket sub.
