1. A method of operation of a navigation system comprising:

  • generating a route with a control unit for navigating to a destination;

    determining a travel deviation based on a current location and the route;

    calculating a total deviation count by incrementing the total deviation count according to the travel deviation during a time threshold;

    adjusting a deviation frequency threshold based on a weak signal flag is determined;

    determining a high deviation frequency when the total deviation count meets or exceeds the deviation frequency threshold;

    determining an error prone scenario based on the high deviation frequency and the deviation frequency threshold adjusted wherein the deviation frequency threshold representing a specified number of occurrences of the travel deviation where the current location deviates from the route within a specified period of time, for comparing to the total deviation count, wherein one instance of the deviation frequency threshold having the specified number of occurrences within the specified period of time different from the specified number of occurrences of another instance of the deviation frequency threshold within a different instance of the specified period of time; and

    enabling an error-prone-scenario switch by varying a user interface based on the error prone scenario for varying an input mode for displaying on a device.
