Abstract: This document describes systems, methods, devices, and other techniques for sharing navigation data among computing devices. The techniques can include identifying, by a first computing device, a second computing device, based on the first computing device detecting an audio signal emitted by one or more speakers of the second computing device, wherein the second computing device is running a navigation application that has been programed to navigate a geographic route. Using information encoded in the audio signal that was emitted by the one or more speakers of the second computing device, the first computing device can determine the geographic route that the navigation application running on the second computing device has been programmed to navigate. A representation of the geographic route can be displayed on an electronic display of the first computing device.
