Calling Sat Nav users -
I have used my Becker sat nav on 3 different cars and noticed that in each case the speed shown on the speedometer was higher by 4mph at 30mph than that indicated on the sat nav (ie speedo =34, satnav = 30 (and it's the same difference at higher speeds)). Now I would have thought that the sat nav would be accurate because it is calculating the speed in real time. Has anyone else noticed this ? What are your thoughts on the accuracy of of sat nav vs. speedo reading ?
