1. An onboard update apparatus disposed in an automotive vehicle, configured to receive a communication from a first communication apparatus and a second communication apparatus, the first communication apparatus configured to communicate with an external server and the second communication apparatus configured to communicate with a portable terminal, the onboard update apparatus comprising:
a control unit configured to determine an adoption of an update program by an onboard electronic control unit installed in a vehicle, wherein
the control unit communicates, through one of the first communication apparatus and the second communication apparatus with an external server outside of the vehicle when a target onboard electronic control unit for updating adopts the update program stored in a predetermined storage area in the vehicle; and
an adoption of the update program by the target onboard electronic control unit for updating is canceled in response to: (1) a communication with the external server being successful; and (2) information relating to cancelation of the update program is acquired; and
the target onboard electronic control unit for updating adopts the update program in response to (1) the information relating to cancelation cannot be acquired; and (2) communication with the external server has failed; and
an identification information for identifying the portable terminal is stored in the predetermined storage area in the vehicle;
the identification information is associated with a vehicle identification number of the vehicle and stored in a storage area to which the external server is capable of referencing; and
the control unit establishes communication with the portable terminal on the basis of the identification information; and
wherein a plurality of pieces of the identification information for identifying the portable terminal is assigned with a priority order for communication with the external server are stored in the predetermined storage area in the vehicle; and
communication with the external server via the portable terminal is performed by the control unit on the basis of the priority order.
