An in-vehicle apparatus for performing a short range communication with a road side apparatus, which performs a hybrid communication including a broadcast communication and a point-to-point communication, is disclosed. The in-vehicle apparatus includes a communication unit and a retry count determination unit that determines whether a count of failure to establish the communication in an activation channel in the communication unit reaches a preset retry count. The in-vehicle apparatus re-selects a communication frequency when the retry count determination unit determines that the count of failure to establish the communication in the activation channel reaches the preset retry count.
