It will only send anonymous data to TomTom, so that they can see/predict traffic jams. The cops were interested in the (anonymous) data, because it allows them to spot where to put speed control (areas with high traffic + high speed).
My box is still on its way: that can only mean good news. Anyway, I consider it money well-spent anyway. For people complaining about something they received: If you don't like surprises, do not enter a surprise sale. Are you also sending complaints every time you do not win in a lottery?
I guess big packages take longer ;)
