For sure speedometer. If the NAV speed were by GPS, Harley would have many bikes going in for warranty repair to calibrate the speedometer because almost always, they're 3-7% fast.

The BOOM! GPS readout is tied to the speedo sensor, not the speed calculated by the GPS unit. When I calibrated my buddies 2014 FLHX speedo, it corrected the GPS readout as well.
My 2015 FLHTK is dead-nuts on and completely stock, depending on what year yours is. First Harley I've owned that came with an accurate speedo.

I know in most cases the GPS will calculate the speed like with my Garmin I used to have in my car. It was a portable unit that had no connection to the vehicle except for power and it would display my speed.
But...
I believe what '14 Limited said earlier about Harley tying it to the speedo because if they didn't they'd get inundated with everybody bringing their bikes in because of differences in speed between the bike and the GPS.
