I noticed when I was using Cruse that if I reset the average speed it shows my current speed but it is not the same as the needle shows. It's out by about 4 or 5 KmH. The GPS we used also shows it's out by the same 4 KmH.

Since the Needle Stepper motor and average speed probally have the same speed signal i think the Stepper motor Calibration is out.

Anyone else have this problem?

 

In the states speedometers are always 2-3 mph off of true speed. Guessing its the same where you are. Also, tire-rim sizes can throw off speed calculations as well. Usually GPS and/or digital read out is accurate to within 1mph

 

I'm fine with it being off by a few Km but I expect both measurements in the car to be the same.
