Car GPS hardware is not as important as software

There are two main types of GPS navigation systems on the market, vehicle-mounted and portable. Compared with the vehicle-mounted type, the biggest selling point of portable GPS navigation is its portability. In addition to navigation, it also has MP3 and MP4 functions. GPS requires not only GPS terminal products but also a network platform. So when choosing GPS, hardware is far less important than software.

The first move depends on whether this company's network is connected to the outside world. Generally speaking, wherever the mobile phone has a signal, the GPS system can cover it, but this is only technical coverage, but the services provided by the monitoring center may not be able to keep up. When choosing a service, the car owner must pay attention to whether the company has established monitoring centers in various places, so that the service system can be connected to the whole province and even the whole country.

The second measure is to buy at a professional and well-known car audio and video store. The biggest cost of GPS is the after-sales service, and only professional and well-known car audio and video stores can guarantee the stability of later services.

The third measure, pay attention to whether the map can be upgraded for free. GPS is an electronic information product, which can be upgraded through technical transformation like a computer. The core part of GPS navigation is the map. Generally speaking, the map needs to be updated once a year at the latest. At present, many GPS brands provide free upgrade services, but some companies do not promise to update the map, or charge a fee, consumers must understand it when buying.
