Car plate - GPS-navigator. Tips for choosing

In order to navigate the entire variety of car plates and navigators, and therefore make the right choice, you need to know the main technical parameters that you need to pay attention to before buying.

In general, the basis of any quality device is its filling, and regardless of the manufacturer.

A good car tablet should have:

• High-sensitivity GPS-receiver;
• Reliable and well-proven hardware component (processor, built-in memory, etc.);
• Modern and proven software (maps).

From these basic parameters, it will depend on how quickly, and, most importantly, the GPS-navigator will make all necessary calculations and determine your location.

What to choose - GLONASS or GPS?

Many are lost in conjecture - which system is better and what to choose for your car. The main difference between these navigational landmarks from each other is the country of origin, that is, GLONASS is Russia, and GPS is America. For our realities, the most practical and useful is an automotive tablet that works with domestic navigation, well, or at least hybrids - GPS / GLONASS.

Do not buy devices that support only GPS-orientation. In connection with recent events, the US government can generally turn off its system on the territory of the Russian Federation, and the only thing a GPS navigator can do is show time and date.

Display

When you select the screen size, you do not need to go to extremes: too small it takes less space, but it's not visible at all, the big one will close the view, although the information on it is better visible. The optimal car tablet is 7 inches or 5, depending on the front panel of the car and the front-view.

Qualitative, and therefore, expensive tablets are equipped with IPS-matrix, which gives a good angular view, compared with cheaper analogs working on the TN-matrix. As for permission, the principle of choosing one is that the more, the better. Almost all five-inch models have a 800-by-480-point development, and seven-inch gadgets are 1024 by 600. For example, the device Lexand SC7 Pro HD has a resolution of 1024 x 600 pixels, and this is enough for a quality picture that you do not need to peer at To disassemble the details.

operating system

The best option is the Android platform as opposed to the Windows operating system. The first has a wider functionality and capabilities, and the software for it is presented in a huge range. In addition, with the help of third-party software can significantly improve the car tablet, which runs on the platform "Android." And the developers of the device first of all release updates for the "green" operating systems, and only then for the "Windows".

Chipset

The chipset in the navigator is responsible for the quality of the signal reception and the accuracy of the determination of coordinates. An enviable popularity and respect for specialists are the chips of the Star series and SiRF. One of the main advantages of these chips is the reception of a reflected and weak signal with high positioning accuracy. They are indispensable in urban conditions, since they allow you to "break through" the dense building of megacities. If you use a navigator in the country, you should pay attention to the MTK chips, which are famous for their low power consumption. The other options have their own list of critical flaws, so you choose to put up with them or choose an expensive but sensible stuffing.

CPU

It does not matter where or how your car tablet is installed: on the headrest, on the panel or on the steering wheel, the main thing is that it quickly processes the information and gives it to you on the screen. The better the processor, the faster it maps and responds to the environment.

The principle of choice is the same as in the case of a screen resolution: more than a digit - better speed. The optimal option for both urban conditions and for the route is 1 GHz. Take for example the same Lexand SC7 Pro HD, which operates at a frequency of 1.3 GHz without any friezes or subsidence on the FPS.

RAM

RAM second in importance after the processor - the more it is, the faster the device works: downloading programs, building routes, etc.

Do not buy a car tablet with less than 512 MB of RAM. Gadgets with 2 GB of RAM on board are considered a universal option: fast loading, lack of friezes and excellent work in urban conditions.

Receiver Channels

To accurately determine the coordinates of the GLONASS or GPS navigator, there is enough more or less confident signal from three satellites. But to obtain information of a broader plan, such as altitude, four satellites are needed.

The number of received channels of the navigator directly depends on its sensitivity and noise immunity - more channels - higher sensitivity. This helps to significantly reduce the time to determine the coordinates, and also contributes to a more thorough processing of reflected and attenuated signals. For example, navigators on Star chips have more than 40 receive channels, and Lexand car plates use 3-4G protocols from at least five satellites.

Battery life

In navigators and tablets use standard lithium-ion batteries with a capacity of 800 to 3000 mAh. Sometimes you can find more advanced and expensive batteries, like lithium-polymer. They work longer, charge faster, but their lifetime is slightly less than ionic analogues. In any case, when choosing a navigation device, be sure to look at the capacity of the battery: preference is best given to a larger number of mAh, and even if it is heavy, but really autonomous.

Navigation software

Below the indicated list of navigation software has long been entrenched in the market and each program has its own features and some nuances. To advise any concrete is very difficult, because one is good in the city, the other on the track, and the third in general is created for mountain travel. You need to choose based on your needs and location.

Popular software for navigation:

• "Navitel" (universal version).
• "CityGid" (urban conditions and large megacities).
• IGo.
• "Garmin."
• "Autosputnik" (ideal for the track).

For a more detailed introduction to each, you can study the detailed instructions on the official resource of the developer of the program and choose the one you need for your needs.

Summarizing

As a conclusion, you can focus on the critical points that must be taken into account when choosing a car tablet or navigator.

Recommendations:

• Choose a device with the support of the domestic GLONASS system or a hybrid GPS / GLONASS;
• A display of at least five inches;
• Gadget on the platform "Android";
• Well-proven chipsets - SiRF and Star;
• Processor with a frequency of not less than 1 GHz;
• RAM - from 512 MB;
• Accumulator battery from 2500 mAh;
• A set of additional functions will not hurt (you never know what will come in handy on the road);
• Proven navigation software (Navitel, CityGid, Avtosputnik and Garmin).

Do not rush to extremes when buying a navigator: a cheap model will "tupit" and quickly land, and taking too expensive does not make sense, since most of the functions of such gadgets are designed for entertainment and have little practicality.
