Navigation guidance system
First Claim
1. A method for providing guidance information with a navigation system, the method comprising the steps of:
- calculating a route to a destination;
outputting the guidance information with an output device of the navigation system to guide a user of the navigation system along the calculated route;
determining, based on a current position of a navigation device of the navigation system, if the navigation device has left the calculated route;
outputting, in response to determining that the navigation device has left the calculated route, a prompt for user input whether output of guidance information with the output device of the navigation system should be suspended;
suspending the output of guidance information;
calculating a new route to the destination substantially concurrently with suspension of the output of guidance information;
calculating an estimated arrival time at the destination based on the calculated new route; and
outputting the estimated arrival time with the output device of the navigation system substantially concurrently with suspension of the output of guidance information.

Abstract
A navigation system may calculate a route to a destination and output guidance information with an output device to guide a user of the navigation system along the calculated route. If it is determined that a navigation device has left the calculated route, the navigation system may prompt the user asking whether output of guidance information should be suspended. If the output of guidance information should be suspended, the navigation system may suspend the output of guidance information and calculate a new route to the destination while the output of guidance information is suspended. The navigation system may calculate an estimated arrival time at the destination based on the calculated new route and output the estimated arrival time while the output of guidance information is suspended.

1. A method for providing guidance information with a navigation system, the method comprising the steps of:
-
calculating a route to a destination; outputting the guidance information with an output device of the navigation system to guide a user of the navigation system along the calculated route; determining, based on a current position of a navigation device of the navigation system, if the navigation device has left the calculated route; outputting, in response to determining that the navigation device has left the calculated route, a prompt for user input whether output of guidance information with the output device of the navigation system should be suspended; suspending the output of guidance information; calculating a new route to the destination substantially concurrently with suspension of the output of guidance information; calculating an estimated arrival time at the destination based on the calculated new route; and outputting the estimated arrival time with the output device of the navigation system substantially concurrently with suspension of the output of guidance information. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A navigation system comprising:
-
a positioning unit adapted to determine a current position of a navigation device of the navigation system; a user interface adapted to output information for receipt by a user of the navigation system and to receive signals indicative of information from the user; and a processing unit adapted to calculate a route to a destination, to generate and output guidance information for guiding the user along the calculated route, to determine, based on the current position of the navigation device, if the user is leaving the calculated route, and to prompt the user, in response to determining that the user is leaving the calculated route, whether output of guidance information by the navigation system should be suspended; where, in response to receipt of a signal indicative of confirmation from the user that the output of guidance information by the navigation system should be suspended, the processing unit is adapted to suspend the output of guidance information by the navigation system, to calculate a new route to the destination based on the current position of the navigation device, to calculate an estimated arrival time at the destination based on the calculated new route, and to output the estimated arrival time. - View Dependent Claims (19, 20)

21. A tangible non-transitory computer readable medium comprising a plurality of instructions executable by a processor, the tangible computer readable medium comprising:
-
instructions executable to calculate a route to a destination; instructions executable to output guidance information with an output device of a navigation system, the guidance information adapted to guide a navigation device of the navigation system along the calculated route; instructions executable to determine, based on a current position of the navigation device, whether the navigation device has left the calculated route; instructions executable to output a prompt, in response to determining that the navigation device has left the calculated route, asking whether output of the guidance information should be suspended; instructions executable to suspend the output of guidance information in response to determining that the output of guidance information should be suspended; instructions executable to calculate a new route to the destination substantially concurrently with suspension of the output of guidance information; instructions executable to calculate an estimated arrival time at the destination based on the calculated new route; and instructions executable to output the estimated arrival time substantially concurrently with suspension of the output of guidance information. - View Dependent Claims (22, 23)
