A vehicle monitoring device of the type including a power source, a sensing module having multiple inputs for sensing events aboard a vehicle producing sensed data, a computer for organizing and storing the sensed data related to the events in an associated memory; and a communication module operatively associated to the computer for transmitting and receiving signals to and from a central location. In a first embodiment, the vehicle monitoring device further includes at least one communication port, operatively associated with the computer, the communication port being designed to send and receive information from a peripheral device, where the computer can open a direct communication link between the communication port and the communication module, so that the peripheral device can be in transparent communication with the central location. In a second embodiment, the vehicle monitoring device further includes an automatic sleep mode system including a low power microprocessor, where the low power microprocessor is operatively connected to at least one of the inputs of the sensing module and where the low power microprocessor is operatively connected to the computer, so that the automatic sleep mode system can power down the computer when the vehicle is turned off and the automatic sleep mode system can power up the computer when the low power microprocessor detects a change of state from the input. The automatic sleep mode system can also power up the computer after a predetermined time interval.
