Claim:
An in-vehicle device comprising: a communication element for communicating with a cell phone in a vehicle; a coupling element for coupling and decoupling between the in-vehicle device and the cell phone via the communication element; a hard disk drive for storing a telephone directory data relating to an individual information and a telephone number corresponding to the individual information; an incoming call notification element for communicating with the cell phone via the communication element in a case where the coupling element couples between the in-vehicle device and the cell phone, wherein the incoming call notification element notifies a passenger of the vehicle about an incoming call from a caller when the cell phone receives the incoming call via an external telephone network, and wherein the incoming call notification element accesses the telephone directory data in the hard disk drive, and notifies the passenger about the individual information corresponding to the telephone number of the caller; a high altitude decision element for deciding whether the vehicle is disposed in a high altitude area having an altitude equal to or higher than a predetermined altitude; and a switching element for setting the hard disk drive in an off-mode based on a decision result of the high altitude decision element in a case where the vehicle enters into the high altitude area, and for setting the hard disk drive in an on-mode in a case where the vehicle passes through the high altitude area, wherein the incoming call notification element stops notifying the passenger about the incoming call and the individual information when the hard disk drive is in the off-mode.
