This is for older car models that do not have built-in navigation or bad navigation. My car is old enough to have a cassette player.
This model is made for a Toyota Yaris from 2001 and the phone inside is an S21 Ultra that would otherwise have been sitting in a drawer.
I have sacrificed the original sunvisor to get the swivel part out and modeled a new sunvisor around it. Since this car is really old it's okay to make these modifications.
So far the driving experience has improved a lot, it is a pretty decent location for a navigation system since you can focus on driving much more easily than having to look down and to the right.

Very good point that I haven´t even considered yet. Hmm. I suppose mounting anything on the steering wheel (where the airbag comes out) is very dangerous.
Theoretically the airbag should hit my face first before the sun visor does. Hopefully neither ever will.
