Firstly, you cannot add new places of interest, you can however add favourites and save them. Secondly, the speed camera alerts depend on the "version" of sat nav card you have in. Having the Ford "version" myself, not the Tom Tom Version, I do sometimes get the speed camera alerts, sometimes!, and because the card isn't updatable, unlike the stand alone sat navs devices. Whenever a new speed camera is added to our road network, it isn't added to the list.
