Hi Alvaro,
and welcome to the forum!
Oh! It is called "Fender up!" in Spain!
I visited your VW website now ...
Seems to be what is called "Groove up!" in Germany.
Both have the same special grey striped seats with the orange fancy seam (and Fender Sound System as standard).
In Germany the M&M is standard for the Groove up!. I had a look at the Spanish website.
There must have been something wrong at your dealer! Navigation is standard in Spain too for the Fender up! !!!
Go to your dealer and ask him about the navigation - which is included as the website says (and I also 100% know from German Groove up!s). You must already have a plastic cover plate on your dash for the M&M navigation???
The Garmin M&M for the "Fender up!" is very special as it shows the Fender logo when turned on.
Go over the Fender up choise and a popup will tell you, that it is included!

Hope you will get the navigation system!
Do you have the plastic cover fot it in your dash? Maybe a worker or a customer at your dealer stole it before the car was handed to you? My dealer kept my M&M at a save place (at the info desk) before it was handed to me. And my dealer also sayed "You have no M&M" and I said: "Yes, I have!". Then the dealer went to the info deask and there it was. Maybe it is somewhere save at your dealer???
Good luck
Andreas
