Im betting that they wanted changes to the shape and size of the unit so that it fits comfortably into the obd2 ports. The ports are in different places and angles under the steering wheel of different cars. My bmw has a hinged door over the obd2 port. My bluetooth obd2 scanner fits fine in my F150 (obd2 port is horizontal) but not so well in my BMW (obd2 port is verticle) and hits my legs if I leave it plugged in while driving.
