there is on mine. You have to set how many mph above speed limit you want the announcement to kick in. It's utter rubbish though. The sat nav on my September 2015 has maps from June/July 2014 hence quite a few speed limits it gets wrong as they have been changed last year I think in the area I drive around. I called Alfa to ask what are the most recent maps and still waiting for a call back but I am not expecting miracles which is disappointing if you consider the fact that on a new car they charge 1000-1500 for sat nav.
