You need Firmware File, Update via SD Card

You need Firmware Patch File, Update via SD Card

A diagnostic tool is recommended

Sorry, I just noticed that you don't have a navigation system. You only have an SD slot, right?

You may also need VCDS or OBD11 pro in order to activate something (I can't remember what, but I did). Not all cars seem to need it but some do

You mean this

And

hallo, ja, nur eine SD in der Mitte des Handschuhfachs

Buy a new used one if you have a coding tool. It's much easier to patch. You can also patch the component protection. You'd also have a navigation system then. But it has to be a mib2_std.

You also have to change the usb port.

Easiest way to avoid all these codings is to add an android auto / carplay box.

I did it on a friends class b and it works Great.

Something like this
