Hi I was wondering thru a hack or anything are we able to program in red light camera's for navigation?  I know some units you buy now have them.  There is a website in which I can download lots of the red light camera''s in the cities around me and I would like to program them into the nav system so If i am approaching them they warn me.  Also with new nav systems they also have the speed limit built into the system to tell you if you are speed is there a hack/mod that allows for that with new map update thanks.
