Chip selection

　　As a navigation product, what we are most concerned about is its ability to receive satellites, that is, the ability to take over information signals. The car GPS sold in the current market mostly adopts the third generation SiRFStarIII chip. This chip has the advantage of capturing and tracking information signals in environments with obstruction and poor weather conditions, exacerbating the disturbance of information signals caused by high-rise buildings. In addition, the black and white of the chip is directly related to the fast and correct black and white when calculating the path. To the same destination, the differences in chips may present different routes, and what we need is the best route.

　　Choose a brand

　　Purchasing products from major brands not only ensures their own quality, but also allows them to enjoy a certain number of years of fee upgrading services. Domestic brands include the Garmin Ren Wo You series we know, the Mio series from Yuda Electric, and brands from Europe and TW such as NAVMAN and Ritai. Although Nokia's participation has also made car GPS more popular. There are countless domestic brands, such as Newman, Patriot, Xinke, Wanlida, Aoshi, Freelander, Leader God, and other various brands. Choosing a brand is actually about choosing after-sales service. When it comes to GPS navigation products, the subsequent handling issues are even more urgent, as the maps are updated in a timely manner. Different manufacturers have different sources of map data, and there are also various methods for updating fees. Good understanding during procurement can avoid some unavoidable difficulties after use.

　　Select a map

　　Electronic navigation maps are another crucial component of GPS navigation systems, and the accuracy of electronic navigation maps directly determines whether car owners can reach their destinations more quickly and easily. In the future market, whether domestically produced or completely imported, the built-in maps of car GPS products are the capital of the only few map merchants in the country, with varying quality and inability to update map information in real-time, which brings inconvenience to users. Generally speaking, GPS navigators from brands on the right track are available for one year of fee updates in cities, roughly calculated in chronological order, supporting around two fee updates. After that, it is necessary to pay a certain cost to update the map. Generally speaking, GPS map providers maintain map updates every six months, and some manufacturers also update data every three months, with an update cost of around 100 yuan. The important method of upgrading is to collect and download through the process, which is also simpler.
