Abstract

The invention provides a communications interface module mountable in a vehicle. The communications interface module includes a first electrical interface for electrically communicating with a control system of a vehicle. The communications interface module also includes a second electrical interface spaced from the first electrical interface for being positioned in a passenger compartment of a vehicle. The communications interface module includes a plurality of communication lines extending in parallel between the first electrical interface and the second electrical interface. The plurality of communication lines exchange a plurality of different communication formats between the first electrical interface and the second electrical interface.
