Press on Hands Free Module.
While the Hands Free Module is in diagnosis mode, the sound input to the microphone unit is output directly through the speaker.

The flash drive needs to be formatted to FAT32 and should not be larger than 16GB. Additionally the head unit can be a bit picky and might not accept all flash drives. If it can't read your flash drive, just try a different one.
Copy the update.package file to the root directory of the USB flash drive.

Step 5 Insert the flash drive

Re-enter the Hands Free Module-Section of the Service Menu.
Press on the S/W-button.
If there is no S/W-button it means that the head unit didn't detect a valid file on the flash drive. This either means that you already have a version newer than the firmware file installed (as is the case for me), an incompatible firmware file, or that the system can't read the flash drive.
Confirm by pressing Yes.
