Issues to be noted when using GPS

Try before you buy

It is best to try it out before purchasing GPS. Although some products are well publicized, there are many problems in operation and use. It is best to be able to listen to the opinions of surrounding GPS users, as well as online comments. If the actual trial is not available at the time of purchase, you can try to set a familiar destination yourself and use the system's simulated navigation function to view the software's route calculation. In addition, you can try to set a relatively uncommon place to check the product's ability to search for addresses. Generally, a multimedia GPS system with convenient operation can complete most of the operations without using the manual.

Distinguish needs

Regardless of the type of GPS, it is not a small expense, so be sure to distinguish the needs before buying. If you do not need frequent use, a mobile GPS or PDA GPS with mobile phone functions is the best choice . If you need to use it regularly, or even use it by multiple people, and you are not very good at electronic products, a multimedia GPS can help a lot.

Consider the cost of use

No matter which GPS system is selected, the cost of later use must be accounted for. Most mobile phone and PDA GPS maps are downloaded online, and the update speed of each map is not the same, so please choose carefully. For multimedia and vehicle-mounted GPS, you need to ask the dealer for the map update frequency and update fee.

Don't use pirated maps

This is a piece of advice for users who choose multimedia GPS. Let ’s not mention the protection of intellectual property rights. Major companies naturally have certain encryption methods for their maps. The latest maps cannot be easily cracked. The version of the map is likely to be worthy of the name. And if there is a product failure due to the use of pirated software, do you think the manufacturer will guarantee you? Now that you have chosen this type of product, don't begrudge the upgrade costs.

Pay attention to anti-theft

Regardless of the GPS system, it should be stored after parking to prevent the windshield from being smashed and the navigation system to be stolen.

GPS is not everything

GPS can only provide you with an "optimal route" that it calculates. It cannot understand when it is a peak period and how much traffic there is on the ring road. Listening to traffic broadcasts to understand current events and road conditions can facilitate route planning.

The GPS system will also make mistakes. Incorrect maps, repeated place names, and system failures may all lead to errors. Therefore, before traveling, you should check the route online if possible. If the GPS system is wrong, you can also find it in time. If you feel an error in GPS positioning while driving, you should stop and ask as soon as possible.
