A vehicle mounted, navigation device is disclosed. This invention combines a global position system (GPS) with an image capturing system into a portable device that can be optimally mounted within a vehicle. The image capturing system detects and interprets visual information in the vicinity of the vehicle to provide the vehicle operator with appropriate navigational guidance assistance after correcting positionning errors embedded in commercial GPS signals. Additionally, the device has the capability to store consecutive frames of detected, visual information so as to enable the device to be used for accident aftermath analysis and the documentation of an event or scene that occurs within the vicinity of the vehicle. The device includes a mounting assembly which enables the device to be used in most automotive vehicles, with the device usually being mounted behind the vehicle's rearview mirror such that a set of directional turning indicators naturally fall within the vehicle operator's field of view. |
