a plurality of wireless transceivers deployed in a vehicle cabin; and
a processor configured to:
determine location of a device, responsive to a determination that a vehicle has been moving for more than a first threshold amount of time or that vehicle doors have been closed for more than a second threshold amount of time, based on received signal strength indicators (RSSI) associated with device signal strength of a signal from the device received by at least two of the wireless transceivers and wirelessly relayed through a central transceiver in communication with the processor; and
store the location and a corresponding possessor identification and location in memory.
