Yes I've noticed the variation between the Speedo and the GPS.

It will vary from car to car and on the speed. At 120 my GPS reads 110.

Basically the manufacture has to ensure that it reads high rather than low. This has to take into account variations due to tyre wear etc..
I noticed that too with my TomTom, but never wanted to risk seeing if ît was the speedo or the GPS that was right.

Either way it can be checked by timing a measured kilometer. At 60kph it should take 60 seconds...
