Selection Guide for GPS Navigation Integrated Machine

"In the old days, Wang Xietang Qianyan flew into the homes of ordinary people." While GPS technology continues to serve the US Department of Defense, ordinary people also slowly enjoy the convenience brought to people by GPS technology. Whether you are in an elevated city with complicated road conditions or a remote mountain trail, whether you are in the hot daylight in the hot sun or the dark winter rainy night, whether you are a road-rider or a road without a sense of direction Lady, as long as you are in a strange place, you need GPS navigation! In the face of the numerous GPS navigators on the market, do you feel that you have no way to start, this article will give you a few tips to help you buy a satisfactory GPS!

Trick one: look at the map-support multiple pictures on one machine

If the hardware is the body of GPS, then the navigation map is the soul of GPS. Because whether it is satellite positioning or path navigation, all functions of GPS must be built on the geographic information provided by the navigation map. The more accurate the geographic information on the map, the more accurate the navigation path generated and the better the GPS navigation performance. . Therefore, when purchasing GPS, be sure to choose products loaded with high-quality electronic maps.

So, what are the factors that measure the merits of navigation maps? Generally speaking, the number of covered cities, information points and the rationality of road planning are the main considerations for judging the quality of navigation maps.

First, the more cities covered, the better. At present, only eight companies in China have Grade A surveying and mapping qualifications and are able to carry out map surveying and mapping work. Among these eight, Kaili De and Datongtong have more complete map coverage. Dadaotong covers about 2,860, and Kay Reed released the country's first "full coverage" map at the beginning of this year, covering all 362 prefecture-level cities and 2,862 district and county-level administrative areas.

The second is the number of points of information (POI) on the map. After all, most users only know the name of the destination and do not know the road where the destination is, not to mention longitude and latitude. To find the destination you want to go on the map to find the best route, this requires the support of massive information points. In this regard, Daotongtong is particularly prominent.

The last is the rationality of road planning. After all, computers are not as good as the human brain. Wherever you know the road, the human brain walks with the computer, and in unfamiliar places, the human brain depends on the computer to go. For pure road planning, the road planning of Intercity Pass is the most reasonable, followed by Dadaotong and Kailide. It is recommended to use Dadaotong and Kailide in South China, and you can refer to Intercity Pass for outbound provinces.

Different GPS navigation software will have different map detail and road planning rationality in various regions, so when choosing a GPS navigator, you must choose a software that can support one machine with multiple maps and can use software such as Dadaotong, Kailide and intercity Machine, such several navigation software can complement the navigation, and make better use of GPS navigation efficiency.

Trick 2: Look at the hardware design-humanized design is the first

The design concept of "Humanization" puts the user's feelings at the core of product design, and indeed brings a more comfortable application experience to consumers. Because GPS is often used when driving, it is very important to choose products that are simple and convenient to operate. In terms of hardware, in addition to observing whether the GPS shell is durable and the interface is tight, also pay attention to the firmness of the GPS car bracket suction cup and fixture to avoid breaking your love machine; at the same time, whether the bracket is easy to rotate should also be considered Range, so that you can easily adjust the angle of view while driving, or perform GPS horizontal and vertical screen conversion, without distracting too much energy.

As the market competition continues to intensify, GPS itself also has more and more rich functions, such as playing videos, music, browsing e-books, pictures, FM transmission, etc. These functions increase the added value of GPS, consumers can Choose according to your needs.

The common display screens of GPS navigation all-in-one machines are 3.5-inch, 4-inch and 7-inch, which can be selected according to your preferences.

Trick 3: Look at the after-sales service-the real after-sale guarantee is the real manufacturer and reputable seller

Now there are 300-400 GPS navigation machine brands, which are uneven and mixed, except for a small number of brands that are produced by the manufacturers themselves, most of them are OEM brands, short-term operation, product quality and after-sales are difficult to guarantee. In order to build their own brands, real manufacturers will do a better job in terms of product quality and after-sales warranty. Unlike those OEM brands, they come and go fast. That's how MP3 products were rotten. As for the reputable sellers, in addition to being responsible for the hardware warranty, it is also related to the GPS map software update service. Powerful merchants will continue to operate and continue to provide customers with navigation map updates. Become an "orphan".
