What should I pay attention to when purchasing GPS products?

　　The GPS positioning system is highly professional and mysterious to many car owners. So, how to choose when buying?

　　"The first thing to look at is the brand. If you want to buy a car, you can check the manufacturer and the brand's founding year online. Generally speaking, brands that can last more than five years are guaranteed." Ms. Shi, from a regular network technology company, said that most car owners are difficult to judge the technology of GPS positioning system, so the best way is to choose a well-known brand with large sales;

　　Secondly, car owners can visit the Internet more often, or inquire about it through relevant GPS forums, and ask the car owners who have used it to see how the reputation of relevant GPS brands is, and understand their advantages and disadvantages;

　　Third, if the car owner has a certain amount of energy and time, he can also go to the office of the GPS dealer.

　　Finally, it should be reminded that after the normal use of the GPS positioning system, the car owner should not forget to pay the relevant data positioning fees to China Mobile or China Unicom on time every month. Although this fee is not high, it may cause signal interruption and positioning failure once it is forgotten.
