Abstract: Navigation application programming interfaces that can be used to obtain navigation information in third party software applications are provided. In one example implementation, an application programming interface (API) can include a first set of instructions associated with a navigator class. The navigator class can specify a plurality of functions to control the implementation of a navigation service by the software application. The navigation service can provide navigation information to a user of the software application. The API can include a second set of instructions associated with a navigator delegate protocol. The navigator delegate protocol can be a delegate of the navigator class. The navigator delegate protocol can implement one or more calls to update the navigation information provided as part of the navigation service.
