I think you are talking OBDII systems, and while they communicate with the ECU, that system wouldn’t need any GPS access. I don’t think it has a direct link with the cambus that would hold the more advanced data. (Which if memory serves, also doesn’t handle GPS.
There is a dedicated port in my car specifically for data logging, but it only records realtime, not past travel. My GPS unit does track “breadcrumbs” if not following a road, but you’d have to interface directly to that computer. since there is no Bluetooth, there is no contact data or advanced privacy weaknesses.
