To provide a vehicle-mounted information processing device which allows a GNSS antenna to be shared well between a telematics device and a navigation device.SOLUTION: A telematics communication unit (TCU) 2 has a built-in global navigation satellite system (GNSS) antenna 12 and switch 13. The switch 13 allows for sending a positioning signal received from a GNSS satellite through the GNSS antenna 12 while switching the destination between an integrated circuit (IC) 11 in the TCU 2 and a navigation device 3. Such an arrangement allows one GNSS antenna 12 to be shared between the TCU 2 and the navigation device 3.SELECTED DRAWING: Figure 1
