Navigator from the rating and review is a necessary companion on the road, it will help you to determine your exact location, down to the street and house number, lay the best route (even taking into account traffic jams, if there is such a function), show a map of the area. Recently, most smart phones and tablets are equipped with GPS-modules, so many drivers prefer to use mobile devices as a “second navigator.
Moreover, in practice, the navigation with the help of this application is not much different from the navigation of specialized GPS-navigator. Smartphones and navigators have their pros and cons, but the choice in favor of one of these devices is not always obvious. However, it is still considered that the specialized devices are faster and the professional maps are more accurate than the maps on smartphones and tablets. In order to help you in your choice, Product-test.ru experts have tested the most popular models of GPS-navigators, with the test results you can find in the test of GPS-navigators.Let’s dwell on car GPS-navigators, what they are, what they consist of and what they differ.How to choose a GPS-navigator?
One of the main advantages of the navigator is the display. All navigators today are equipped with a color touch screen display.
They differ from each other, first of all, by the size: as a rule, they are from 4.3 to 7 inches diagonally. In fact, the choice is up to the amateur, but 4.3 inches may seem small, the picture is small, and it is harder to get into the right icon, and 7-inch seems too bulky and obscures the view, in addition, these “extreme” diagonals border with displays of dangerous to navigators competitors – smartphones from the bottom line and tablets from the top.
In addition, the displays differ in resolution, there are navigators with a resolution of 480×272, 800×480, 320×240. No special comments are needed here: the higher the resolution, the higher the clarity of the image. By the way, the highest ppi among the tested navigators is 187 dpi, which is not so impressive, especially after some tablets, but enough for a navigator.
Diagonal size options for navigators
Thirdly, it is the viewing angle of the best car gps navigation, which depends on the technology of the display matrix. Most often it is a cheap TN matrix, with viewing angles of no more than 130-140 degrees. Before you purchase we recommend you to assess the viewing angles by eye, to check whether the colors are inverted when tilting the device left-right and up-down, as a rule, the vertical viewing angle will be much smaller.
And finally, anti-reflective coating in the gps best rating is the name says it all, in the road always want the information from the display can be easily read, and the light falling on the screen should not interfere with viewing information. It is rather difficult to check it straight away, but you can switch the navigation programs on the navigators and look at them under the same light source in order to get some comparative evaluation of the display: which one glare more and which one less.
