Regarding data visible on the SkyView moving map when interfaced with a GNS430:
The SkyView moving map will only should course guidance, route legs, etc. from the SkyView moving map inputs. Currently that input consists of direct-to a single waypoint. Upon release of our Navigation Mapping Software upgrade, you will have multi-leg route-planning capability in the SkyView map.
External GPS devices outpoint only GPS position and course deviation information. They do not output their multi-leg route depictions for display in the SkyView moving map. In the future, we may add the capability to import a multi-leg route definition from external sources such as the GNS430/530, but that feature has not yet been scheduled for development.
