1. A method of operation of a navigation system comprising: determining a navigation component based on comparing a traversal content to a stored content for identifying an object type; determining a content discrepancy based on the navigation component present in the traversal content but unidentified in the stored content; generating a content filler with a control unit based on the content discrepancy for identifying the navigation component representing a road type different from the road type included in map information; updating the map information by replacing the road type originally in the map information with the content filler representing a digitized instance of the road type for including in the map information to present on a device; updating a travel route to include the content filler representing the road type for connecting a disjointed instance of a road within an un-updated instance of the map information to reach a destination; and determining a traffic condition of the travel route based on a vehicle count meeting or exceeding a count threshold wherein the traffic condition representing no traffic when the vehicle count is below the count threshold, the traffic condition representing light traffic when the vehicle count meets the count threshold, and the traffic condition representing heavy traffic when the vehicle count exceeds the count threshold for presenting on the device.
