How to clean up the car navigation memory shortage if it is the running memory of the navigator, there is no way to increase it. Storage memory can be realized by expanding SD card. What should I do if the car navigation memory is insufficient? If the car navigation memory is insufficient, you can delete useless data or replace the memory card with larger memory. Generally, only old-fashioned car machines will encounter the problem of insufficient memory. Generally, the old car will download the map to the memory card and then insert the memory card into the car. Other functions in the car also need to occupy a certain amount of empty memory card space, and the memory will be insufficient after a long time. If the memory is insufficient, you can replace it with a larger memory card, or you can unplug the memory card and connect it to the computer to clean up useless data. This old car machine is almost no longer used by drivers. Many people either choose to replace the smart big-screen car machine or use mobile navigation directly. The price of replacing a smart big-screen car is around 700 yuan 1000 yuan. This smart car, like a smart phone, is equipped with Android system, comes with its own memory and does not need an external memory card. It can download music online and use some navigation applications to navigate. The navigation accuracy of smart cars is similar to that of mobile navigation app, and the navigation accuracy of smart cars and mobile navigation is much more accurate than that of classic cars. Classic cars often need to download the latest version of the map to ensure the accuracy of navigation. @20 19
