GPS radar detector can not only be used for speed detection radar alarm, but also for traffic light electronic eye warning; Whether the electronic eye is detected by a radar wave laser or by a ground sensing ring, the GPS radar detector can give an alarm. Compared with the radar detector and electronic system, the GPS radar detector can also identify the direction of the electronic eye. For example, the electronic eye in the opposite direction or the cross direction, it will not give false alarms, but you need to pay attention to updating the data online during the use. Another point is that if you find something not marked on the map, you'd better mark it on the map according to the "point of interest", so that you can only use it for reminders in the future. In addition, the GPS radar detector can also set the alarm advance, such as 300 meters or 500 meters; If the car did not exceed the speed limit at that time, you can not give an alarm to save trouble. In addition, no matter whether you have an electronic eye or not, the GPS smart dog can remind the car owner of the speed limit in this section and whether it is exceeding the speed limit now. In addition, the GPS radar detector can also be used to find gas stations, toilets, parking lots, etc. In addition, it has all the recording functions of general GPS. In addition, some GPS smart dogs can report the names of highway exits, gas stations, roads, etc
