Abstract

This invention discloses an inquiry system and a communication apparatus thereof. The inquiry system comprises a first communication apparatus and a second communication apparatus. The first communication apparatus is used to send an inquiry signal to the second communication apparatus. The second communication apparatus has a Global Positioning System (GPS) function and a predetermined map database. After receiving the inquiry signal, the second communication apparatus compares the predetermined map database with the inquiry signal to generate corresponding map information. The corresponding map information is then transmitted to the first communication apparatus. The invention can make the communication apparatus without GPS function to achieve the purpose of inquiring map information.
