Vehicle information output device and vehicle information output system

The present invention provides a vehicle information output device and a vehicle information output system, with which it is possible to more flexibly determine information to be output during a period from the time when a power supply is switched on to the time when the power supply is usable. The vehicle information output device (100) includes an output unit (110) configured to output information to inside of a vehicle, a starting unit (104) configured to execute starting processing in a case that the power supply is turned on, a communication unit (120) configured to communicate with an external device via a network, a communication control unit (134) configured to acquire output information stored in the external device via the communication unit, and an output control unit (136) configured to cause the output unit to output the output information acquired by the communication control unit before starting processing by the starting unit is completed. 提供能够更灵活地决定在从电源接入后到成为能够使用为止的期间输出的信息的车辆用信息输出装置、车辆用信息输出系统
