DESC: The Whistler RLC-360 GPS Module integrates with the Whistler Pro 3600 radar detector and enhances the Pro 3600 with many GPS based features. With the Whistler RLC-360 module, the Pro 3600 will be enhanced with a nationwide database of speed and red light camera locations and will provide alerts as you approach these devices. These traffic cameras are constantly being added, and the RLC-360 can be updated via the Internet using the included USB cable. The addition of the RLC-360 module also activates other features of the Pro 3600, including the ability to display your vehicle's current speed and to automatically activate "auto quiet" and set filter modes based upon the vehicle's speed.
