These are some diagrams from the workshop manual related to the audio unit and sub-display. Small differences in the wiring of the audio unit - no differences in the wiring of the sub-display between with or without navigation. But what is not shown in the diagram is that the two audio units send different signals to the sub-display. So my guess is that only the navigation audio unit can properly drive the small sub-display that comes with the navigation display and only the non-navigation audio unit or the connects2 harness can drive the non-navigation display. The navigation unit itself doesn't seem to get involved directly with the data sent to the sub-display, even though it has direct communication with the climate control unit.
