ok I have a GPS which is cool, but I found this online and wondered if it works like it says it does, basicly you down load poi maps that are updated as needed. when your moving around in your car, it 'alerts you' to 'known' speed traps and traffic cameras.
Sounds cool ( I want it), does anyone on here use something like this? I think there are a couple of sites that do this. this is the one I was looking at. Phantom Alert Review
