Audi a4l b9 upgrade dual navigation problem without green mib #24
Description
Hello, riders, there is something wrong with upgrading the dual navigation mib of the locomotive. In this case, everything is normal in front of the picture, but in the green project, there is no second mib. After reading all the posts and comments about the upgrade, I don't know what is wrong. The file is also the file corresponding to the locomotive patch and copied to the patches folder. The sd card is used, the card slot 1 is inserted, and the card is not pulled out. The sd is not write-protected and the format is correct
