Buy the regular manufacturers of navigation systems

Was guiding to the owners, did not expect because of their own "Lost" and bring more trouble to the owners. Recently, CCTV exposed Navigator market irregularities. According to reports, the quality supervision and inspection center of national communications and navigation equipment on the 13 mainstream manufacturers of 18 types of satellite navigation products were detected, the results of only three manufacturers of 5 products by even less than 30% pass rate.

More frequent economic exchanges with the large-scale construction of the popularity of cars and roads, intercity, navigation systems are becoming increasingly important set of accurate positioning, navigation and entertainment features in one navigation to better meet the needs of the owners, a car basic equipment. Today, however, the uneven quality of navigator, many problems are frequent, consumers are gradually lost its original trust.

In recent years, with the rapid increase in car ownership in China, the navigation industry also will be rapid development. According to the China Electronic Chamber of Commerce said that the annual increments of the car navigation breakthrough 400 million units, large and small, nearly a thousand brands on the market once, navigation systems hardware, software quality and map updates can not keep up and other issues are emerging, seriously affecting the the consumer's use.

Outdated map, resulting in the navigator often guidelines for owners to avoid costly mistakes. Many navigation systems but also in the larger cities, but to some small towns, the electronic map is not so muddled. Even a good signal map is correct, not necessarily indicate the correct path. The original navigator have the path computation function, but not all of car dvd player and in car dvd player the Navigator product has a perfect path recalculation. Deviate from the planned route due to various reasons, so many owners, the navigator is always only repeat the "U-turn instructions to recalculate a new path, but not for the actual road.

The survey found that the navigator hardware and software of poor quality, slow map updates, product reliability and low in three areas. Navigator error there are two main reasons, first, due to road traffic conditions change, navigator map does not update the guidelines resulting from deviation; Another reason is the navigator installed is pirated map. In addition, GPS positioning requires simultaneous reception of at least three or more satellite signals, but high-rise or viaduct is likely to make the receiver to lose lock of some satellites, and also make the data have a greater deviation.
