I did it at work to day
After installing the latest software version.
Let me try again tomorrow.
I don't know how Precise you need to be.
I just pressed the screen in the lower area.
No need, it worked... it seems that it's dependant on how fast and how precise you are when tapping the screen...
It doesn't worked for me using the volume knob at first, so I used the volume buttons from the steering wheel and it worked, then tried again with the volume knob and after some tries and fast tappings, it worked.

For those that have problems with that, try to use the volume buttons from the steering wheel instead of the volume knob, you can be more steady when tapping the screen.

Also I've been tapping this area:
32135


Thx.

In final step for me i have to press several times. But its works. What is the engeneier code? (Not the dealer code)
 
Dealer mode on 2020... yes, engineering mode no. I don't know the code, putting the hh:mm as code doesn't work on this device.

Worst is that it says "Engineering mode" when inputting the password, so it must ve accessed that way. 2400 its only for dealer mode.

No autotest button found in system category on dealer mode.

Sorry to dig up an old post but engineering mode code for this is 0428
 
Can someone summarise how to activate Dealer Mode and engineering mode on the 2020 model?
  1. Press the Settings button
  2. Choose General -> System info -> Version info/Update
  3. In a quick sequence set volume to level 7 and tap to the right of the word „Update“ on the screen, then set volume to level 3 and tap to the right of the word „Update“ on the screen,, then set volume to level 1 and tap to the right of the word „Update“ on the screen,
  4. Password is 2400 for dealer mode or 0428 for engineering mode.
