Previous Destinations Button Is Dim and Not Selectable in the Enter Destination By Screen (Grayed-out)

Previous Destinations button is dim and not selectable in the Enter destination by screen (grayed-out)

The vehicle on the navigation unit may be new, or the client deleted the destination. Without a stored previous destination, the system can't route to a previous destination. Enter a destination, and allow the system to route to it. After the trip, the Previous Destinations button will be selectable.
