Nowadays, GPS navigators are installed and become the new hobby of many car owners. The donkeys who returned from the "May 1st" long holiday have all talked about GPS, which is both joy and trouble. For example, GPS facilitates the way to find the road, but there are also such as the long waiting time for searching for satellites, the wrong way to find or It's not the most suitable way. In fact, the current GPS navigation technology is relatively mature, the level of domestic manufacturers is similar, so the probability of hardware failure is not very large, the key is to pay attention to software during use, and overcome some bad habits.
Trouble one: it takes longer to search for satellite signals
Solution: external antenna
When using GPS, the easiest time to search for satellite signals is longer, and even the car has been out for a few minutes and the GPS has not yet navigated. After the GPS navigation system is turned on, there is a response period from searching for satellite signals to starting navigation. Generally, it ranges from tens of seconds to two or three minutes. Each brand will be different due to differences in production technology and chips. But if you are still searching for satellite signals five minutes after turning on the phone, you have to check the GPS navigator.
First of all, it depends on whether the lithium battery of the navigator is charged. It can be used for 6 hours after charging for 2 ~ 4 hours. The built-in adapter can be used to connect to the car during the inspection. Use the 12V power provided by the car Re-search; if there is no problem with the power, it is necessary to check the GPS usage environment, whether it is under shelter, and whether there are strong electrical electromagnetic sources around it, such as radar stations, TV transmission towers, mobile phone base stations, etc. Because GPS has good reception ability only in an open environment, bad weather may reduce the strength of the signal but does not affect navigation, and the shielding of buildings, metal components, and electromagnetics can also affect the reception of signals, and even many cars The explosion-proof thermal insulation film attached will also affect the signal reception. If you are in this environment, you can connect an external antenna, and place the external antenna on the roof of the car to enhance the signal reception capability.
Trouble two: the difference between the navigation map and the actual
Solution: Upgrade the map
Regarding the failure of the navigation system to find a suitable route, the name of the route reported and the actual discrepancy, this has nothing to do with the positioning of the GPS, mainly because the map used by the navigation system has a problem, which may be a cracked version Pirated maps), or because the maps have not been upgraded for a long time. The map software used by general brand manufacturers is genuine and provides a free upgrade after use, but some people choose to use the cracked version of the map because of the price.
So, how often do GPS navigation maps need to be upgraded? This mainly depends on two points. One is that if there are more changes in the place names, road names, and actual names provided by the map during use, it means that the map needs to be upgraded. The second is that after a period of use, map manufacturers can provide more accurate and detailed maps, and it is best to upgrade to facilitate navigation. At present, the general manufacturer will charge a fee of about 150 yuan for upgrading a map.
Trouble three: data loss cannot be navigated
Solution: strict drug detection
During the use of the GPS navigation system, another problem that will arise is that the data is lost and navigation is impossible. Generally, it will appear in three situations: the first is to directly plug and unplug the SD card or external power supply, external audio and video system that stores the map software without shutting down, so the GPS navigation system is best like a computer. Turn off and plug in and out of various devices. The latter two cases are related to the MP3, MP4 and other entertainment functions provided by the current GPS navigation system. They may be infected with viruses when downloading songs online, which may damage the map software, or they may mistakenly delete other contents of the SD card when deleting songs Delete. So you need to pay attention to these operations when using GPS navigation system for entertainment.
In addition, regarding the problem of direction indication when using GPS navigation, two modes are provided in the GPS navigation system. One is the "right south and north" mode displayed on the screen according to the commonly used "up north and down south" method. Car owners who are not too strong recommend choosing this mode, because it allows you to determine the direction according to the method of going north to south; the second is the "car-turning" mode, which is the direction of the map on the screen. It is the direction of the head of the car instead of north. At this time, you can observe the small north arrow in the upper right corner of the display screen to distinguish the direction. The needle with a clear color points to north.
Finally, the owner needs to protect the display screen of the GPS navigation system, because the price of GPS differs by hundreds or even thousands of yuan, a large part of the difference lies in the level of the display screen, so use a soft cloth to wipe the dust to avoid sharp Hard objects scratch the display.
