Navigation system
First Claim
1. A car navigation system which receives information from an information service device by using a communication line, comprising a communication part which communicates through said communication line, a display part, a plurality of screen switch buttons, and a processing part which accepts setting from an operator and performs the processing, wherein said processing part has;
- a screen change processing means for allowing the operation screen displayed in said display part to change according to the content of the operation on said plural screen switch buttons by the operator, the operation screen under the display, and the layered structure of said plural operation screens, the operation screens to receive the setting from the operator being provided hierarchically; and
a communication control processing means which establishes communication line between said information service device and said system by controlling said communication part when the information from said information service device is needed in order to process according to the setting given by the operator through each of a series of operation screens displayed in said display part, and cuts off said communication line after receiving said information.

Abstract
In a navigation system, display screen handling PG 2032 prepares hierarchically a plurality of operation screens to receive the setting from the operator, and changes the operation screen displayed on display 208 according to the content of the operation to operation button group 207 by the operator, the operation screen under the display, and said layered structure. Further, communication control PG 2032 controls cellular phone 30 through cellular phone IF 204 when it is necessary to receive the information from the information service center 10 in order to process according to the setting given by the operator through each of a series of operation screens displayed on display 208, and establishes the communication line between information service center 10 and this system. And, after information is received, the communication line is cut off.
