Abstract
A radar detecting circuit adapted to be on the vehicle detects a radar signal and selectively provides a radar detect signal in response to detecting the radar signal. The vehicle's speed is determined such as indicated by a tachometer signal or a global positioning system (GPS) receiver adapted to be on the vehicle and providing a GPS speed signal representative of the vehicle speed. An alarm responsive to both the radar detect signal and the GPS speed signal provides an alarm indication when a radar signal is detected and the vehicle speed is above a preset maximum, such as the speed limit. The operator indicates the present maximum speed via an input device such as a keypad or via voice recognition software.
