Buick will not upgrade the Gaode map. The version 3.2 of the German map that comes with Yinglang car can't be upgraded. Even if you upgrade to version 5.1, restart and return to version 3.2. The reason why it will be upgraded and restarted is to revert to version 3.2. Mainly because this thing is at work, the startup system vendor partition verification of Android system means vendor and supplier. All the files stored in this folder are suppliers, and I hope you can see the mirror images of the files. Perform system vendor partition verification every time you start up.

Car navigation uses satellite navigation, which is more accurate than the guide rail of mobile phone and receives signals faster. Especially in mountainous areas or tunnels, the response speed of car navigation is indeed higher than that of mobile navigation.
