An internal GPS receiver compares your location with the built-in database, and displays an alert on the large, 1.6-inch color OLED screen if you're in danger of approaching a red light camera or speed camera.

Comes with 1-year of free database updates, after which it'll cost you $19.95 per year. You can still use the device without an active subscription, but there's probably not much point if the database ceases to be current.

Hammacher Schlemmer is selling the device for $199.95. If you can wait a little while, it looks like Amazon is taking pre-orders for the exact same device for just $131.99.
