Traveling by car, GPS is not credible

In the spring of March, Yangchun went to the peak of outings and took family and opened their own cars for short-distance fun. In addition to formulating travel plans and carrying emergency equipment, it was necessary to have a GPS navigator - everything depended on him. However, with the recent hot "GPS door" incident, we have questioned the credibility of GPS.

The causes of this series of problems are as follows:

1. The quality of navigation products is worrying. At the press conference of the first China Satellite Navigation Product Certification held recently, the quality inspection results issued by a professional certification organization for navigation equipment in China showed that 13 mainstream manufacturers and 18 models of satellites were inspected. Among the navigation products, only 5 products from 3 manufacturers passed its certification and the passing rate was less than 30%.

A sample survey conducted by China Electronic Chamber of Commerce Consumers also showed that with regard to GPS navigation product complaints, the software category accounted for 46%, and the hardware failure category also accounted for 42%.

2. The lack of software features The operating software loaded by the brand navigators is different, and various problems often occur. According to the above-mentioned technicians, some of the knockoff products have poor navigation software and often crash, making them annoying. The survey conducted by the relevant certification body also revealed that some navigation software was compiled unreasonably and often drove the driver to bypass the road; in addition, some navigation software lacked the path reset function, causing the navigator to repeat only once it deviated from the predetermined route. Please "turn around" without resetting the path and eventually cause a crash.

3, overblind from GPS

The misleading GPS incidents on the Internet, which caused the root cause of all these problems, may not be just because the maps in the navigator are not updated and the owners are blind to navigation.

For these, the Xiaobian of China Manufacturing Network recommends:

1, choose a good GPS navigator we need to pay attention when buying: First of all navigator to see clearly, the screen should be clear, voice sound quality is good; followed by follow-up service is very important, the map is the soul of the navigator, the map on a regular basis The upgrade is particularly important; at the end of the day, there are many navigation devices on the market and the functions are getting more and more fancy. When we purchase a navigation device, we must know that the purpose of the navigation device is navigation. Therefore, we recommend choosing the product with the best navigation function.

2. Appropriate use of mobile phone navigation or road sign reference Now that the mobile phone is fully functional, and some mobile phones themselves come with genuine navigation, owners of large-screen smart phones can use mobile phone to download genuine professional navigation software as a navigation device, which can also ensure that the line is up to date And the current roads are marked with road signs at the intersections, and proper reference is beneficial and harmless.

3, less to see more than the way to navigate the wrong way to "Lu Chi," have to use less navigation. For some long lines, we better be able to remember the route. Moreover, from a safety point of view, the use of eye light to see the navigation will also distract the driver's attention, especially when the navigator will always appear some routes are unclear, the response is too slow, this time involves the vehicle change line, etc. When operating, it may not be possible to remind in advance that the operation under the rush of the vehicle owner is likely to bring danger to the vehicle.
