The combination of a global positioning satellite system (GPS) and a radar detection unit, in wireless communication with the GPU, for tracking and determining the speed of a vehicle. The system may be manually activated, or more preferably activated by an external source of radar signals, such as may be emitted by a police "speed trap". The unit includes means for recording and storing speed data of the vehicle, and to alerting the operator of the vehicle to a "speed trap" situation.
