An information distribution center includes a controller that searches for a route from a departure place to a destination place as a search route and searches for access points on the search route. The controller selects, based on distribution information, a first access point that can communicate with a mobile terminal apparatus when a vehicle is turned on and that corresponds to a first portion of the distribution information and selects, based on distribution information, a second access point along the search route that corresponds to a second portion of distribution information. The controller then transmits the first portion of the distribution information to the first access point and transmits the second portion of the distribution information to the second access point.
