Most car owners who are unfamiliar with car navigation products buy them by directly determining the brand and price (the brand and price recommendations will be introduced in the next few issues). Of course, in addition to these methods, car owners can actually identify the good and bad in the process of trying out products (if it's an online shopping channel, you can only choose trustworthy products).

Before the special car audio-visual navigation became popular, some businesses made a profit by selling general-purpose machines, because general-purpose machines are very simple to copy and assemble, and can be produced into finished products through labeling. However, with the rise of special-purpose cars, general-purpose machines have long faded out of the mall. Imitation and assembly can be avoided for all brand products.

Select a special audio-visual navigation product for the special car. Because we can't disassemble it to see the internal workmanship of the product, we can only make a rough judgment from the appearance and use. First, we can start from the panel docking and whether the keys are smooth.

After startup, we can intuitively feel the clarity of the screen, and the resolution can be known from the parameter configuration. However, many screens are less anti glare, and the owner can see the frequency screen photosensitive effect directly from the light, because most machines are difficult to clearly see the delicate picture in the sun, so the owner doesn't have to worry about it.

Feel the sensitivity of the touch screen with your hand. Xiaobian has tried to press the function icon several times without response, and then can see whether the machine is stuck by playing the game.

There is another point that will affect the product function, that is, the heat dissipation of the product, especially in high-temperature climate. Because the environment in which the vehicle itself is located is not very ventilated, the heat dissipation of the product itself is more important, otherwise it will appear such phenomena as crash and jam.

Summary: in fact, only the appearance and use can roughly judge the workmanship of the product. For example, it is difficult for us to judge whether the anti-seismic function and radiation of the product are overspent. Car owners can only try to choose brand products with fine workmanship and after-sales guarantee.
