And for the record (not trying to be an @ss at all btw) here are a couple sites talking about how the gps and red light cameras come into play
"Cheetah GPS locates red light cameras, photo radar"

"This GPS detector is not a navigation system but is does use the same SiRF Star III technology as the top nav units like Garmin and TomTom.

And I see what your saying kc5f about how gps doesnt really detect the cameras. But the gps has a big role in letting you know where they are.
And motoguy128...nvm lol, there is a section on the site above ^ that says pretty much the same thing you did lol.
