GPS Angel has an on-board database of thousands of speed camera and red light camera locations in the US.
As you drive, GPS Angel checks your vehicle's location to this database and provides visual and audible warning when you are approaching a camera.
The camera database is updated regularly and you can download updates over the Internet by connecting GPS Angel to your PC with the included USB cable and the GPS Angel Manager software. GPS Angel includes FREE unlimited lifetime updates to the database. Other GPS detector products charge a fee for updates, which can be over $100 per year. GPS Angel has no update fees and is the most accurate and affordable red light camera & speed camera detector.
