GPS navigation device purchase

When each car owner chooses to purchase a GPS navigator for his own car, it is difficult to choose a brand that faces a wide range of domestic brands. It is necessary to consider the practicability of the navigator, and some must match the appearance of the car with his own car. Especially for a car owner who does not know much about the GPS navigator, it is even more blind to its practicality. Here Xiaobian gives you a few points to highlight when choosing a GPS navigator.

1, choose the chip, as a navigation product, the ability to receive star, that is, the ability to receive signals is the most important. Most of the on-board GPSs currently on the market will use third-generation chips. The advantage of such chips is that they can capture and track signals and mitigate signal interference caused by high-rise buildings in the event of blockage and poor weather conditions. In addition, the quality of the chip is directly related to the speed and accuracy of the calculation of the path.

2, choose the brand, buy the big brand products not only their own quality assurance, but also can enjoy a certain number of years of free upgrade service. The selection of brands is also a matter of selection and sale. For GPS navigation products, subsequent service issues are even more important. Different vendors, different sources of map data, free update methods are also varied.

3. The selection of maps and electronic navigation maps are another important component of GPS navigation. The correctness of electronic navigation maps directly determines whether the owner can reach the destination more quickly and easily. In the current market, whether it is domestic or fully imported, the built-in maps of on-board GPS products are nothing more than the resources of only a few map providers in China. The quality is also uneven, and often it is not timely to update the map information to the user. Inconvenience. In general, the regular brand GPS navigators will provide free updates for one year, or calculated by the number of times, and support about 2 free updates.

4, choose the speed, the speed mentioned here includes the speed of the satellite, the speed of the boot and the reaction speed. Due to the need to pay attention to safety at the time of driving and the car is moving at a high speed, the speed can improve the accuracy of vehicle navigation, at the same time, it can save the user's operation time and save time and worry.

5, choose the battery, although GPS products will basically provide the car power supply, but under special circumstances the role of the battery can not be ignored. How long the battery has endurance, that is how long the navigator can continue to use after disconnecting the charger, is also a criterion for assessing the goodness of the navigator. Life time reflects the energy efficiency of the machine and also reflects the overall performance of the machine. It is best to choose a navigation device with a built-in lithium battery capacity of more than 1000mAh when purchasing, which usually provides a standby time of 7 to 8 hours.

6, choose appearance, including appearance, antenna, screen, sound and accessories. Car GPS antennas are usually built-in. The equipped suction cup holder should pay attention to whether the suction cup is smooth and whether the size is large enough to prevent the suction cup from falling off when the vehicle bumps; it is also necessary to pay attention to whether the bracket adjustment angle is convenient and the length of the power cord is appropriate. The large sensitivity of the touch screen is also crucial. The screen is too small to allow the driver to concentrate; insensitivity can delay timing and affect driving mood. Car GPS is used to listen to navigators, relatively speaking, the sound may be more important than the screen. The volume should be as large and clear as possible without breaking sounds.
