1. A method of determining whether a handheld communication device (HCD) is located inside a vehicle, comprising the steps of:
- (a) receiving at a central facility a request to locate the HCD;
(b) sending a message from the central facility to the vehicle with an instruction to begin listening for an acoustical signal that is generated by the HCD;
(c) sending a message from the central facility to the HCD with an instruction to generate the acoustical signal;
(d) receiving a response from the vehicle at the central facility that indicates whether or not the HCD generated the acoustical signal; and
(e) transmitting a message from the central facility to a user of the HCD indicating whether the HCD is located inside of the vehicle based on whether or not the vehicle detected the acoustical signal.
