The invention relates to a navigation device for providing warnings when a detection point of a speed trap is approached, comprising a processor unit (11) arranged to communicate with memory unit (12 - 15) and to receive positional information from a positioning device (23). The memory unit (12 - 15) may comprise a speed trap database, comprising at least one detection point (P1) of a location of a speed trap. The navigation device (10) is arranged to provide a warning when one of the at least one detection point (P1) is approached. The memory unit (12 - 15) is further arranged to comprise at least a further detection point (P2) associated with at least one of the stored detection points (P1), both relating to a same point to point speed trap. The navigation device (10) is arranged to provide a warning when the further detection point (P1) is approached or has been passed.

La présente invention concerne un dispositif de navigation pour émettre des avertissements lors de la détection d'approche d'une zone de vitesse contrôlée, comportant une unité de traitement (11) agencée pour communiquer avec une unité de mémoire (12-15) et pour recevoir une information de position provenant d'un dispositif de localisation (23). L'unité de mémoire (12-15) peut comporter une base de données de zones de vitesse contrôlée, comprenant au moins un point de détection (P1) d'une localisation de zone de vitesse contrôlée. Le dispositif de navigation (10) est agencé pour fournir un avertissement lors de l'approche d'au moins un point de détection (P1). L'unité de mémoire (12-15) est également agencée pour comprendre un autre point de détection (P2) associé à au moins un des points de détection stockés (P1), les deux concernant une même zone de vitesse contrôlée entre deux points. Le dispositif de navigation (10) est agencé à fournir un avertissement lors de l'approche de l'autre point de détection (P1).
