Navigation equipment Mount for VW up!

Hello, I’ve had a new take-up for over 2 weeks! unfortunately without Maps & More. I still want to have a navigator in the car. I don’t want to stick it to the windshield. Now I’m thinking about whether there are possibilities to mount the navigator in the vents (rather unlikely, as it’s not the usual slots). Do you have a ignite idea or experience? Already a thank you in advance.
