The Pyle PLNVB25 Universal Navigation system consists of a navigation computer with DVD-ROM drive, and a GPS system with an antenna and SD Card slot and speaker. Just download the maps onto the included SD Card, and plug this into the RGB or composite video input of your car monitor, and you will get turn by turn directions via voice prompts and through the directions given on the screen.
This navigation system tracks your where-abouts in real time, and it speaks out every turn and direction in real time, so you don't miss any turn, and instead of concentrating on directions, you can relax to some music while driving, without any worries of getting lost. If for any reason you make a wrong turn, don't even sweat it, because this sophisticated GPS system will automatically re-rout you to the quickest route. The voice prompt feature will speak out every turn, with a warning when the turn is coming up. This way, you don't need to look at the screen.
The built-in memory will store previously used addresses, and you can quickly get directions to that area, with clicking a couple of buttons (Even if you don't know your current location)
If you want to go to a gas station, or restaurant, and don't know which, don't worry about it! This GPS system lets you search a point of interest such as a gas station or restaurant, in a certain town or state, and you can choose which one you like best.
The navigation will work with any car monitor. If you have a dual zone monitor that will give you many more options such as displaying navigation in the front, and watching a movie in the back monitors or vice-versa.
