RADAR DETECTOR WITH NAVIGATIONAL FUNCTION
First Claim
1. A navigation and police activity warning device comprising:
- a receiver section receiving signals generated in the context of law enforcement activity,a warning section responding to the receiver section and providing a warning if a received signal correlates to a law enforcement signal, the warning produced by the warning section varying in relation to a vehicle location derived from a position determining circuit,a navigational system providing a graphical display and navigational functions, the display including a display of navigational information including indications of stored locations for which the device stores data that is used by said warning section in varying the warning produced in response to a law enforcement signal.

Abstract
A GPS enabled radar detector dynamically handles radar sources based upon previously-stored geographically-referenced information on such sources and data from the GPS receiver. The detector includes technology for determining the location of the detector, and comparing this location to the locations of known stationary sources, to improve the handling of such detections. The detector may ignore detections received in an area known to contain a stationary source, or may only ignore specific frequencies or may handle frequencies differently based upon historic trends of spurious police radar signals at each frequency. Notification of the driver will take on a variety of forms depending on the stored information, current operating modes, and vehicle speed. The detector may be also incorporated within a general purpose navigation device.
