Doubt 1: GPS navigation search information is very slow.

In fact, there are several kinds of slow search. The first is that the input error affects the search results. Doing this repeatedly will make people feel that the GPS navigator is not easy to use.

In addition to the user's reasons, the machine will also cause slow search. After all, GPS navigator is not the high-performance computer we use, so there must be a gap in calculation speed. Just like cars, GT-R runs faster than ordinary family cars, and the engine performance is here! In addition, the software of GPS navigation system is also an important factor affecting the slow search. Some GPS navigators support fuzzy search, which greatly improves the accuracy of search.

Doubt 2: Different GPS schemes have different routes.

Consumers who often use GPS will definitely ask this question. I also go from A to B. Why do different GPS give me different routes? At present, the GPS navigation on sale will provide 3-5 different routes when calculating the route, such as high speed priority, shortest distance and so on. However, different software providers have different road calculation and planning rules, and different GPS basic settings will lead to different calculation methods. This makes different navigators plan different routes between the same two points, but whoever is good or bad can only see whose calculation method is more perfect and scientific.

Doubt 3: the vehicle position is inconsistent with the GPS display position.

Friends who have used GPS navigation will definitely have this experience. When you are driving at high speed on the highway and know that you are about to leave the exit through GPS navigation, it often happens that your car has already left the exit for a long time, but according to GPS navigation, it was still on the road just now. This situation is often called "drift" figuratively.

The reason why this happens is that the hardware problem of GPS navigator leads to the slow refresh rate of GPS, so you must choose products with fast refresh rate when purchasing GPS navigator. At present, the refresh rate of commonly used GPS navigators in the market is 1 time /0. 1 second, and if the refresh rate is too slow, there will be "drift".

It can be seen that there are many factors that determine whether a navigation product is easy to use, and there are also many reasons for the use effect of navigation products. Although navigation is a well-known product category, many details behind it are unknown. I hope to help car owners polish their eyes and choose navigation products that suit them.
