The first control unit is configured to transmit the position information received by the position information reception unit to the second control unit through the communication line, and the second control unit is configured to convert a datum of the position information received from the first control unit by the first conversion process unit. ## Claims ### Claim 1 An in-vehicle system comprising: a position information reception unit configured to receive position information from a satellite positioning system; a first control unit that includes the position information reception unit or is connected to the position information reception unit; a communication line connected to the first control unit; and a second control unit that is connected to the first control unit through the communication line and has a first conversion process unit configured to convert a datum of the position information, wherein the first control unit is configured to transmit the position information received by the position information reception unit to the second control unit through the communication line, and the second control unit is configured to convert a datum of the position information received from the first control unit by the first conversion process unit. ### Claim 2 (depends on 1) The in-vehicle system according to claim 1, further comprising: a communication unit configured to perform wireless data communication with a server including a second conversion process unit configured to convert a datum of position information from the satellite positioning system, wherein the first control unit includes the communication unit or is connected to the communication unit, and is configured to transmit the position information received by the position information reception unit to the server through the communication unit. ### Claim 3 (depends on 1) The in-vehicle system according to claim 1, further comprising a communication unit that performs wireless data communication with a server, wherein: the first control unit includes the communication unit or is connected to the communication unit, and is configured to transmit the position information received by the position information reception unit to the second control unit through the communication line; the second control unit is configured to convert the datum of the position information received from the first control unit by the first conversion process unit and transmit the position information with the datum converted to the first control unit through the communication line; and the first control unit is configured to transmit the position information with the datum converted received from the second control unit to the server through the communication unit. ### Claim 4 (depends on 1) The in-vehicle system according to claim 1, wherein the datum of the position information received by the position information reception unit is a global datum, and a datum into which the datum of the position information is converted by the first conversion process unit is a datum of a region where a vehicle equipped with the in-vehicle system is located. ### Claim 5 (depends on 1) The in-vehicle system according to claim 1, wherein the in-vehicle system does not include any position information reception unit configured to receive position information from the satellite positioning system, other than the position information reception unit. ### Claim 6 An in-vehicle system comprising: a position information reception unit configured to receive position information from a satellite positioning system; a first control unit that includes the position information reception unit or is connected to the position information reception unit; a communication line connected to the first control unit; and a second control unit connected to the first control unit through the communication line, wherein the first control unit has a first conversion process unit configured to convert a datum of the position information, the first control unit is configured to convert a datum of the position information received by the position information reception unit by the first conversion process unit and to transmit the position information with the datum converted to the second control unit through the communication line. ### Claim 7 (depends on 6) The in-vehicle system according to claim 6, further comprising a communication unit configured to perform wireless data communication with a server, wherein the first control unit includes the communication unit or is connected to the communication unit, and the first control unit is configured to convert the datum of the position information received by the position information reception unit by the first conversion process unit and to transmit the position information with the datum converted to the server through the communication unit. ### Claim 8 (depends on 6) The in-vehicle system according to claim 6, further comprising a communication unit configured to perform wireless data communication with a server including a second conversion process unit configured to convert a datum of position information from the satellite positioning system, wherein the first control unit includes the communication unit or is connected to the communication unit, and is configured to transmit the position information received by the position information reception unit to the server through the communication unit. ### Claim 9 (depends on 6) The in-vehicle system according to claim 6, wherein the datum of the position information received by the position information reception unit is a global datum, and a datum into which the datum of the position information is converted by the first conversion process unit is a datum of a region where a vehicle equipped with the in-vehicle system is located. ### Claim 10 (depends on 6) The in-vehicle system according to claim 6, wherein the in-vehicle system does not include any position information reception unit configured to receive position information from the satellite positioning system, other than the position information reception unit. ### Claim 11 An in-vehicle system comprising: a position information reception unit configured to receive position information from a satellite positioning system; a first control unit configured to use, as a first datum, only position information obtained from the position information reception unit; and a second control unit configured to receive from the first control unit the position information obtained from the position information reception unit and use the position information as a second datum. ### Claim 12 (depends on 11) The in-vehicle system according to claim 11, wherein the in-vehicle system does not include any position information reception unit configured to receive position information from the satellite positioning system, other than the position information reception unit.
