I drive a friend's car, I want to know if his car is a satellite positioning system, in the absence of his case, how can I know?
Open the car on the DVD you can see that there is not a GPS option, and there is installed, and if not, it is only a simple DVD
A little; look at the back of his car is not equipped with a small probe, there is probably a big GPS.Second: look at his car there is no display, usually 9 inches screen.Third; there is no antenna.
GPS positioning has been widely street, 1, Qianduoyi, can buy a navigation, and see if there is no LCD screen can be found on the LCD screen.
Correct upstairs:1 car butt probe is reversing radar or camera, and GPS unrelated.2.GPS general built-in antenna. In short, the outside can not see.3 large screen LCD screen is a necessary condition for GPS, but not a sufficient condition...Conclusion: depending on the host system interface there is no GPS menu.
Light from the appearance of the car is not recognized whether the installation of GPS positioning. You can look at the dashboard below the dashboard has a wiring harness, a look to know whether to install.In addition, the display of each car are different, generally open the main interface should be displayed on a GPS navigation, no words to set inside to find. If there is no set inside, you can determine the car does not have GPS navigation function.Car GPS positioning system is based on GSM/GPRS network and GPS satellite positioning system, SMS or other means of remote vehicle positioning or monitoring. With mileage statistics, ACC detection function, power failure alarm function.
