Does anyone out there face the problem that the speedo meter reading is different from the GPS speed reading? Like when your speedo meter reading is at 110km/h, the GPS reading is only at 105km/h or already over the speedo meter reading like 120km/h?

Fantastic thread! minus the comments from users which does not read and simply post based on their own findings, not facts.. ah sometimes ignorance is a bliss..

i'm driving myvi ezi..last week using my bro's n82 gps..the reading is almost exact.

That's where you are wrong. PDRM does not give you 10km/h difference. That's because they are capturing your speed from an angle. For speedo cameras to be accurate, it has to be shot directly in front of the car. Any angle will give you a variance. So actually, they are not giving 10km/h difference, it is just that they are always capturing a slightly slower speed than your actual speed. Furthermore, in most cars, there is a meter variance of up to 5% faster, meaning that your speedmeter is faster by up to 5% at 110km/h.

This combined with your actual speed taken at an angle, people end up with the urban myth that the police give you 10km/h more before saman. That is wrong because if you are travelling at about 120km/h on your speedometer, your actual speed is most probably around 115km/h with the police capturing your speed at 110km/h.

Agree, I drive kancil, the GPS reading are same as the speedo meter. When I drive the old saga, which have about 10km/h faster then the GPS. Its even worst for motorbike, about 15-20km/h different.

Conclusion that Perodua had the most accurate speedo meter. So don't speeding, there is not tolerate variance for Perodua driver.
