TomTom Navigator shows the POI's on the screen, but when you're driving you can't watch your PDA's display all the time.
That's why CheckPOInt was written: To give you an audible warning when you approach a POI.
As you can see in the screenshot, some of the overlays you can download contain the coordinates of speed cameras. Therefore one of the purposes you can use CheckPOInt for is to warn you when you approach one. Not that you're speeding all the time; but just that single occasion when you're in a hurry...
And best of all it's Freeware
