GPS is used for specification of coordinates consisted of a group of satellites located in the Earth’s orbit.
In this case, a sputniks themselves should be within sight, and their number should be at least four (three, if only length and width are to be defined).
That is why positioning accuracy depends not only on the technical characteristics of the navigator (receiver sensitivity, antenna quality, calculation algorithms, etc.).
But the disposition of the terrain is also important (in a garage, tunnel or on a narrow street with high-rise buildings, the signal simply does not reach your navigator) and even weather has meaning (in cloudy weather and rain the signal fades) .
There are 2 main characteristics: screen and the processor with the GPS receiver chip.
All car navigators are equipped with color touch screens. In obsolete and/or budget models, the diagonal of the screen is up to 4.8 inches – the readability of navigation information, in this case, is not high.
It is better to choose models with at least a 5-inch screen or more. These navigators are larger and occupy more space on the windshield of the car, but they are more convenient to use.
The processor and the GPS receiver chip. This “duet” ensures the reception of navigation signals, their processing, and output to the screen.
The expensive navigators have multi-core processors with high speed; they can be used for playing games, watching movies and surfing the Internet.
Using the navigation program on a powerful “iron” is more pleasant – when scrolling the picture is smaller, the image is drawn faster.
Some navigation programs will work annoyingly slowly on weak processors (with a frequency of up to 600 MHz).

Navigator is a fairly complex electronic device, equipped with a powerful processor, a large screen, and an operating system.
That is to say, this is an ordinary tablet computer that can and should be used not only for navigation: video, photo and music playback.
Medium and high-end models, as a rule, have support for all common media formats (JPEG, MP3, AVI), which will allow you to pass the time in a dead traffic or waiting to watch your favorite movie.

Navigators equipped with a built-in FM-transmitter, allow you to broadcast the soundtrack on a regular recorder, and therefore, listen to it with the help of high-quality car speakers.
When choosing a navigator, it is very important to understand that this is not just a piece of hardware, but a full-fledged hardware and software system, in which both components are important.
On whatever advanced platform your device is based, it will not be able to fully satisfy your requests if it has navigational software with an inconvenient interface and no address search.
Similarly, the most expensive and high-quality maps installed on a navigator with a morally outdated GPS chip cannot save you from the annoyance associated with the permanent loss of satellite signals.
That is why it is worth choosing devices from well-known manufacturers, long and seriously proven in this class.
And they themselves will take care of selecting for your navigator reliable electronic components, a modern GPS-module, a productive processor.
And also there is a sufficient amount of memory. It is in the complex and provides a comfortable navigation.
I can recommend first of all focusing not on the initial models, but on the middle class with the optimal price/opportunity ratio.
