1. A system comprising:

  • a processor circuit configured to be plugged into an on board diagnostic connector of a vehicle;

    an auxiliary device configured to operate independently of said vehicle, enabled to generate positional data internally using at least one of satellite signals and Wi-Fi location information, and enabled to establish a link with said processor circuit;

    wherein, (i) upon establishing said link with said processor circuit, location services provided by an operating system of said auxiliary device respond to applications running on said auxiliary device with navigational information provided by said processing circuit instead of the internally generated positional data and (ii) the navigational information provided by said processing circuit is more accurate than the positional data the auxiliary device is enabled to generate internally; and

    a computer readable storage medium embodying computer executable instructions, wherein said computer executable instructions, when executed by said processor circuit, enable said processor circuit to (i) communicate with one or more busses of said vehicle via said on board diagnostic connector, (ii) generate said navigational information using one or more of said satellite signals and motion-related information obtained by said processing circuit from said one or more busses of said vehicle, (iii) convert said navigational information to a format usable by said auxiliary device, and (iv) communicate said navigational information to said auxiliary device via said link.
