just google "BMW nav prep cradle"
On the BMW F850GS, the factory GPS/sat nav cradle plugs directly into a dedicated 3-pin connector located under the front dash/panel area, typically on the right-hand side near the back of the instrument cluster or headlight frame
You usually need to remove or loosen the windshield and front dash trim panel to comfortably see and reach the connector.
