first embodiment

[0049] First, the present invention will be described.

[0050] FIG. 1 is an illustrative diagram schematically showing a configuration of a navigation system according to the first embodiment of the present invention.

[0051] In FIG. 1, reference numeral 5 denotes a communication-type navigation terminal for being mounted on a vehicle, reference numeral 70 denotes a cellular phone base station for performing radio communication with a cellular phone, reference numeral 80 denotes a map data delivery center for delivering map data, and reference numerals 90.sub.1 to 90.sub.n denote GPS correction base stations for calculating GPS correction data.

[0052] First, the navigation terminal 5 will be described.

[0053] The navigation terminal 5 obtains map data delivered from the map data delivery center 80 and then gives guidance of a route to a destination, using the map data obtained. Further, the navigation terminal 5 stores rough map data covering large geographic areas in advance. The rough m...

second embodiment

[0122] Next, the present invention will be described.

[0123] FIG. 10 is an illustrative diagram schematically showing a configuration of a navigation system according to the second embodiment of the present invention. Elements that have the same functions as those in FIG. 1 according to the first embodiment are indicated by like reference numerals and characters.

[0124] The navigation system according to this embodiment is different from the navigation system according to the first embodiment in that the map data delivery center 80 has a function of transmitting to the navigation terminal 5 data on an advertisement requested by an advertiser to be advertised. Then, when coupon information for a commodity discount is issued to a user who has seen the data on the advertisement, issue of the coupon information is notified to a terminal 93 of the advertiser.

[0125] As illustrated, the map data delivery center 80 according to this embodiment comprises a server 81', the map DB 82, the point ...

Abstract

In a communication-type navigation system for downloading map data according to the present invention, a reduction in the amount of map information to be transferred, correction of a position measured by a GPS, and delivery of advertisements are effected. In this system, a terminal 5 stores rough map data in advance. Then, when detailed map data is required, it is downloaded from a map data delivery center to the terminal 5. Further, together with the map data, GPS correction information is delivered to the terminal 5 from the map data delivery center 80. Still further, coupon information associated with an advertisement is displayed and an electronic mail on the coupon information is issued, by the map data delivery center.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a navigation apparatus for giving route guidance using map data delivered through communication or broadcasting. The invention also relates to an information delivery apparatus for delivering map data using communication and broadcasting.[0003] 2. Description of the Related Art[0004] Recently, there are proposed various navigation apparatuses for giving a vehicle guidance on a route to a destination.[0005] In JP-A-9-325040 and JP-A-10-246641, for example, there are disclosed navigation apparatuses for downloading map data from a data center. Since the navigation apparatuses of this type eliminates the need for installing therein a storage device such as a CD-ROM unit, miniaturization of the apparatuses can be effected. In addition, the most up-to-date map data and real-time information can be obtained from the apparatuses.[0006] In JP-A-9-325040, there is disclosed a navigation system in which a route search is ...
