ECE countries do have a Speed Limit Retrofit kit available, so long as the vehicle has the KAFAS camera. If your car has Lane Change/Departure Warning or Forward Collision Warning you have the necessary camera.
The retrofit is essentially an FSC code plus some coding. It's available in Conversions/Retrofits within ISTA/P at your dealer. You just have to pay for it.
