Most car owners who are unfamiliar with navigation products choose and buy through the method of directly determining the brand and price (the introduction of brand and price will be introduced in the next few issues). Of course, in addition to these methods, car owners can actually identify the advantages and disadvantages in the process of trying out products (if it is an online shopping channel, they can only choose more reliable products).

Before the special audio-visual navigation for special vehicles became popular, some businesses made a profit by selling general-purpose machines, because general-purpose machines are easy to copy and assemble, and can be produced into products after labeling. However, with the rise of special vehicles, general machines have long faded out of the market, but all brand products can be prevented from imitation and assembly.

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 application. First of all, you can start from the panel docking and whether the keys are smooth.

After the machine is turned on, we can intuitively feel the clarity of the screen, and the resolution can be known from the parameter equipment. 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 see the delicate picture clearly in the sun, so the owner does not need to tangle with this.

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 play the game to see if the machine is stuck.

Another point will affect the product function, that is, the heat dissipation of the product. Especially in high-temperature weather, the heat dissipation of the product itself is more important because the environment in which the vehicle is located is not very ventilated. Otherwise, it will appear such phenomena as crash and jam.

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