Navigation system and memory medium storing the position data of the specific facilities

摘要

Memory mediums storing position data of specific facilities that can be read as position data of a destination on the map data of a vehicle navigation apparatus are distributed to users. When a user sets or inserts this memory medium to a fixed location of the navigation system, the position data of the specific facilities is read and set as the destination. Then the vehicle navigation apparatus starts route guiding to the destination. Arriving at the destination, the user can shop or obtain the benefit of discounts at the facilities (the shop) by using coupons for those shops, also stored on the memory medium.
