I have an old mobile phone running the GPS software by @MrChops and the Android head unit has its own GPS software, they usually agree with each other (the difference seems to be due to a lag and is usually 1MPH different) but the the speedometer like yours will register 33 when the GPS says 30MPH.Are they accurate?
They reason I ask is during a jaunt through the Devonshire countryside the GPS on Google maps it said we were doing 30 and the speedometer said 33?
The dial has been changed btw
The council move a speed indicator between the approaches to my estate and it agrees with the phone GPS. I've had the police point things at me from bridges over the road and I'm yet to get a letter about speeding, I often set the cruise control on motorways when the phone GPS reads 70. I've even passed patrol cars when doing this without being pulled over.
I'd say they're accurate enough given the wiggle room that is generally allowed on speed limits.
