1. A navigation device, comprising:
- a processor; and
a memory storing computer readable instructions that, when executed by the processor, implement;
an instruction receiving unit adapted to receive, from an external device, a processing instruction;
a processing unit adapted to perform processing according to the instruction received by the instruction receiving unit; and
an output unit adapted to output information obtained as a result of the processing performed by the processing unit;
wherein the computer readable instructions, when executed by the processor, further implement a communication unit adapted to communicate with the external device through a communication network;
wherein the instruction receiving unit is adapted to receive a processing instruction from the external device through the communication unit;
wherein the output unit is adapted to send output information obtained as a result of the processing performed by the processing unit to the external device through the communication unit;
wherein the computer readable instructions, when executed by the processor, further implement a state notification unit adapted to send, to the external device, a judgment specifying whether the navigation device is in a state allowing receipt of a processing instruction from the external device;
wherein, once the navigation device has been turned on and has been in communication with the external device, the state notification unit is adapted to send the judgment independently of an action of a user of the navigation device; and
wherein, when the navigation device is in a process of performing a route guidance, the judgment sent from the state notification unit specifies that the navigation device is not in a state allowing receipt of a processing instruction from the external device.

Abstract
Provided is a navigation technique which allows a person other than a user who received a route guide to operate a navigation device through an interaction process. The navigation device is characterized by being provided with an instruction reception unit, a process unit, and an output unit. The instruction reception unit receives an instruction for a process from an external device. The process unit executes a process in accordance with the instruction received by the instruction reception unit. The output unit outputs output information which is obtained as the result of the process executed by the process unit.

9. A program for a navigation device, wherein:
-
the navigation device comprises a control unit; and the program makes the control unit carry out; an instruction receiving step, in which a processing instruction is received from an external device; a processing step, in which processing according to the instruction received in the instruction receiving step is performed; and an output step, in which output information obtained as a result of the processing performed in the processing step is outputted; wherein the program further makes the control unit carry out a communication step to communicate with the external device through a communication network; wherein the instruction receiving step receives a processing instruction from the external device via the communication step; and wherein the output step sends output information obtained as a result of the processing performed by the processing step to the external device via the communication step; and wherein the program further makes the control unit carry out; a state notification step to send, to the external device, a judgment specifying whether the navigation device is in a state allowing receipt of a processing instruction from the external device; wherein, once the navigation device has been turned on and has been in communication with the external device, the state notification step sends the judgment independently of an action of a user of the navigation device; and wherein, when the navigation device is in a process of performing a route guidance, the judgment sent by the state notification step specifies that the navigation device is not in a state allowing receipt of a processing instruction from the external device. - View Dependent Claims (10, 11)
