Car navigation systems market turmoil

Do not know the road are not afraid of cars, GPS navigator on the line "- if you have such thoughts, you'd be wrong. Recently, the first Chinese satellite navigation product certification results conference held in Beijing, from the release detection point of view of GPS satellite navigation products overall level of quality worrying, only less than 30% on-board satellite navigation products through inspection and certification.

Find their way, and frequently call a U-turn, and even crashes ... many car owners, car navigation systems, and perhaps to suffer such a painful experience. In the end this is a bad signal, the map did not upgrade, or product quality problems  The release from the hand, directly pointed out where the problem is. It is understood that since October 2011, China Electronics Technology Group Corporation 54th Research Institute Certification Center accepted the application for certification of the company's products, the quality of the 13 mainstream manufacturers, 18 types of satellite navigation products in accordance with the relevant provisions of the inspection and test, and 19 districts in the country to carry out a real sports car validation.

However, results show that even these informal enterprises and the production of car navigation systems, the product is uneven, there are many problems. Navigation and positioning accuracy, for example, vary considerably with the actual location, often even lost the signal. Some maps are outdated, resulting in the navigator often pointing to the owners to avoid costly mistakes. In the previous news, there have been the original owners follow the navigation to the destination, but later went to another city joke.

Even a good signal, the map is correct, not necessarily instructed to walk the right path. The original navigator have the path computation function, but not all of the Navigator product has a perfect path recalculation. Many owners a variety of reasons to deviate from the scheduled route, the navigator is always only repeat the "U-turn instructions, but not the actual road to re-calculate the new path, and ultimately can not be used.

Relatively genuine car navigation systems, many owners was more like to buy a knockoff. Why knowing the the knockoff problems, some owners still want to buy it  Freeloaders psychological, misguided reasons. Reporter survey found that in the computer in the city, many of the Purchasing Guide will make use of "crack" version consumers. For example, ask What is the difference with genuine Purchasing Guide said, these cottage GPS navigation systems installed inside the "crack" version of the map, not only as the genuine map normal use, can also be a free upgrade to the store. Genuine upgrade, should be charged relative to one liter like the cost of hundreds of pieces, this is undoubtedly very attractive knockoff.

According to industry sources, the crack maps are simple synthesis of the electronic map, the accuracy is poor,Main products: car DVD player and car dvd , are with good quality. often referred to as the wrong path. Cottage navigator key components and parts of poor quality; the poor reliability of navigation software, the preparation of unreasonable and flawed; low product reliability problem. It is understood that the provisions of the State Bureau of Surveying and Mapping, only those with Class A mapping qualification of enterprises to produce electronic map GPS map, the map of the remaining manufacturers in the strict sense is piracy. The big brands on the market, use their own particular brand of genuine map. Like some knockoff, often two or three maps can be chosen at random, but its reliability can be imagined.
