My in car gps system shows it doing 75 mph when the speedometer (in dash)shows it doing 80, 66 mph when doing 70 on the speedometer. So if doing a minimum speed posting of 45 mph I would be doing only 43 mph on the speedometer. Toyota claims that the speedometer is with in tollerance and will not address the issue.
