Has anyone upgraded a 16-18 SV with the standard 5” non touchscreen radio to the factory navigation unit out of the higher models? I’ve got the factory nav unit and gps antenna on the way, but after tearing into it, it appears that the base unit has a 3 plug harness while the navigation unit has 2 plugs. Anyone know where to get a harness to convert or a wiring diagram and a source for plugs so I can build one?

Any luck on a plug and play swap?
