Navigation user interface

A first device, comprising:

• one or more processors;
• and
• memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for:
• receiving, from a second device, a request to initiate navigation based on one or more user inputs received at the second device;
• based on the request to initiate navigation, monitoring for the occurrence of event conditions related to the navigation;
• while monitoring for the occurrence of event conditions related to the navigation, determining that an event condition related to the navigation has been met, wherein the event condition corresponds to a respective suggested action;
• in response to determining that the event condition has been met:
• transmitting, to the second device, instructions to present a first alert at the second device at a first time indicating that the event condition has been met that serves as a prompt to perform the respective suggested action;
• and
• presenting, at the first device at a second time, a second alert indicating that the event condition has been met that also serves as a prompt to perform the same suggested action;
• and
• wherein:
• the second device is different from the first device,
• the second alert is different from the first alert, and
• the second time is selected so as to be spaced apart from the first time by at least a predetermined delay time period.
