Engineering Menu on W176

[nikolas]

I have a W176 that originally came with NTG 5.1 Audio 20, and later on I had NTG 5.1 Comand retrofitted by a specialist.
My question is related to the "engineering menu" and access to it.
When I had Audio 20, I could enter "engineering menu" by pressing "hang up + 1 + ".
The resulting screen looked like this:


However, this combination does not work on Command. I can only access the menu called "Dealer" using the combination "hang up + 7 + 9", which looks like this:


Does Comand have an engineering mode? And if so, how can someone access it? Is any activation required?
Thank you in advance!

Have you tried to activate the menu using the routine? On most new devices, the engineering menu is disabled by default.

Can you please tell me how can I do that?

As effect said, it's disabled by default and you'll need Vediamo to enable it. Might be a good starting point.
May I ask what you use the engineering menu for? Just curiosity.

My question is more out of curiosity than a real need to perform a specific operation. As I mentioned earlier, I found it strange that I could access the engineering menu from the Audio 20, but not from COMAND.
