Here is a short youtube video of the nearest feature. This was today after updating to the latest firmware. It works the same as the last few firmware updates.

Are you sure you are updating the firmware on both the vario display as well as the "computer"? The vario and display update automatically when you insert the updates on the sd card. The "computer" must be updated via the password menu with 89891 as a password then follow the prompts to update. It takes several steps and will then confirm a successful update.
