a selector that selects content corresponding to at least one position associated with the determined content acquisition region from the content list;
a prefetcher that acquires a first part of the selected content;
an acquisition determiner which determines whether a remaining part of the selected content will be referred to based on a position of the mobile unit subsequent to acquisition of the first part of the selected content, and thereby determines whether to acquire the remaining part of the selected content; and
an acquiring section that acquires the remaining part of the selected content when the acquisition determiner determines to acquire the remaining part of the selected content,wherein the acquisition determiner calculates a time it will take to acquire the remaining part of the selected content, determines whether the mobile unit will be located within a predetermined distance from a position corresponding to the selected content after a period of time corresponding to the time it will take to acquire the remaining part of the selected content, and when determining that the mobile unit will be located within the predetermined distance from the position corresponding to the selected content after the period of time corresponding to the time it will take to acquire the remaining part of the selected content, determines to acquire the remaining part of the selected content.

Abstract
The present invention is to store a content list that stores at least one pair of content related to a position and the position in relation to the content, determine a content acquisition region to acquire the content based on a current position, select content in relation to a position associated with the determined content acquisition region from the content list, acquire part of the selected content in advance, determine whether remaining part of the selected content will be referred to based on a position subsequent to the part of the selected content being acquired, thereby determining whether or not to acquire the remaining part of the selected content, and when determining to acquire the remaining part of the selected content, acquire the remaining part of the selected content.
