1. A method for determining the position in a vehicle of a first device in communication with a microprocessor, the method comprising:

  • receiving, at the microprocessor, a first set of inertial data from at least one sensor of the first device;

    receiving, at the microprocessor, a second set of inertial data from at least one sensor of a reference device disposed within the vehicle; and

    determining, using the microprocessor, the position of the first device in the vehicle based on at least one difference between the first set of inertial data and the second set of inertial data, wherein determining the position of the first device comprises detecting whether the first device is located on a driver side or a passenger side of the vehicle;

    wherein the reference device in the vehicle is one of the following;

    a device fixed at a reference point in the vehicle;

    a device connected to an on-board diagnostics system;

    a component of the vehicle;

    a second device within the vehicle;

    ora second device at an unknown position;

    wherein the device fixed at the reference point is a cigarette lighter adapter configured to transmit data to the microprocessor.
