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.
