Vehicle navigation system belongs to one of the high-end configurations of vehicles. However, in recent years, it has occurred from time to time that the navigator has led car owners astray, and some car owners have been fined for this. Why does the navigator present unreliable guidance information?Jiangmen vehicle navigatorThe manufacturer believes that there may be three reasons for this:

The first reason is that the electronic map is not updated in time. "At present, the maps of some navigators in shopping malls have been updated once a quarter, but there are still many brands that are updated once a half year, and some even 1 ~ 2 years. Obviously, this update speed can not keep up with the pace of urban development and road changes." then, why don't map suppliers accelerate the update frequency? The reason is the high cost. It is understood that every time the electronic map is updated and upgraded, the manufacturer will consume a lot of time and cost.

The second reason is the formation of vehicle film, especially the components contained in some metal films will disturb the GPS signal, resulting in inaccurate positioning or lag, and then affect the accuracy or sensitivity of navigation.

The third reason is that many navigators in shopping malls use pirated software maps, which are not as clear and accurate as genuine maps, and the system is not stable, sometimes even incompatible.

In addition, the failure of car owners to upgrade the navigation software in time is also an important factor. It is reported that the on-board navigator is mainly divided into two types. One is the vehicle machine products produced by the original factory, which have been installed in the vehicle before leaving the factory; The other is to add products, which are generally purchased by car owners from the market and then added to the car. No matter which product is used, it needs to be upgraded continuously, and the owner has to pay the corresponding fee.
