INFORMATION PROVIDING DEVICE, INFORMATION PROVIDING SYSTEM, INFORMATION PROVIDING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM

An information providing device includes a memory configured to store estimated destinations on a map in association with scheduled activity venue names, and a processor. The processor is configured to: acquire a user's scheduled activity venue name from user's activity schedule information; read a user's estimated destination corresponding to the user's scheduled activity venue name from the memory; provide an in-vehicle device with information for presenting a route to the user's estimated destination; acquire information regarding a stay place from the in-vehicle device; and store the stay place, in the memory, as a new estimated destination in association with the user's scheduled activity venue name, when the user's estimated destination differs from the stay place.
