I looked for a few videos on You Tube but only found a couple so far. Watched them and finally figured out what most of the indicators across the bottom of the video means. Steering, brakes, turn signals, RPM, speed, what gear you are in, voltage and the usual date and time. I am not sure about the circle with the "A" in it, maybe throttle position? Or the % below is actually the throttle open percentage maybe, not sure.
I know that OBD is supposed to be somewhat "standardized" but wonder if it works like this on all makes and models?
Looking at what comes in the unboxing video looks to be plug and play; you get power from the OBD port.
