Audi a4l b9 upgrades dual navigation problem green mib

[zuotian1988]

Hello, riders, there is something wrong with the upgrade of the dual navigation mib. The picture shows that everything is normal in the red front. When it comes to the green project, I read all the posts and comments about the upgrade, but I don't know what is wrong. The file is also the corresponding file of the locomotive and copied to the patches folder. The sd card is used, and the card is not pulled out. The sd is not write-protected, and the format is correct. I don't know why, so I am in trouble.
