The GPS speedo showed 189km/h.
The orange thing in the picture is to hide where I took this picture.

I am at 77 MPH on digital speedometer at 3000 RPM in 6th gear (as I recall, I think it should be 75 based on calculations). Also with the radar signs that post your speed that have been around town, it seems that I am 2-3 MPH higher that I actually am.
Another way to check speedometer/odometer accuracy is to measure actual mileage over a known distance. My trip computer is about 20 miles more than my odometer at over 8000 miles, (which does not make sense to me).

with Garmin GPS it indicates my speedo reads 2mph faster than I'm going
speedo = 80 mph
gps = 78 mph
speedo = 80 mph
gps = 78 mph
