Hi - unless there is a way to upload your own POI catagories? (not sure - only had car for a few days)
if you can then there are POI compatible formats for all types of cameras on the GPS World website (£20 subscription for 12 months) - this is how we used to do it with the early TomTom navigator CE software on Compaq/HP Ipaq's
My only comment would be that speed camera databases need to be updated often, and the best also rely on user submitted content for mobile units/traps - if it was an included POI category then it would quickly become obsolete, which is probably one of several reasons why I can see why it's not included.
I'd recommend something like trapster (free) for andriod/iphone as this is community updated so as accurate as reasonably possible
