Content Delivery In Real-Time Guided Navigation

Methods, systems, and apparatuses, including computer storage media, for content delivery in real-time guided navigation. A device can be configured to identify location information for the device and provide navigation instructions to the device based on at least the location information and an identified destination. The device can access scheduling information indicating an availability of a user of the device, and determine based on the scheduling information, whether to provide content related to one or more places of interest. When it is determined to provide the content, the device can determine a timing for output of the content in relation to output of the navigation instructions.
