摘要： A vehicular information receiver is coupled to a portable device that receives information by paying a communication fee based on a unit packet fee. The receiver sets reception factors that affect the amount of data received by the portable device. An expected fee calculation unit calculates an expected communication fee based on the unit packet fee and an expected amount of data, which is based on the reception factors. A display unit displays the reception factors and the expected communication fee, which can be viewed by a user. Accordingly, the user is able to view the reception factors that determine the amount of data to be received and the expected communication fee associated with the data to be received, before such data is received from the portable device, thereby avoiding unexpected increases in communication fees.
