I have a 2019 CX-5 and find that my polarized sunglasses dim down the HUD a lot. I read one review which claimed the new Mazda 3 HUD was a lot better in this, but would like to hear some real life feedback from people here.
I had a '17 Mazda 3 GT with the pop up HUD and now my '18 6 Signature with the windshield displayed HUD. Polarized glasses affected both of them. I could notice a difference from just moving my head, I'm wondering if driving position vs HUD projection angles has an impact on visibility as well.
I’m resurrecting this old thread as my question is applicable.
My darling wife gifted me a really nice pair of polarized sunglasses, which as you can imagine, has a negative effect on the HUD.
I have tried numerous ways and orientations of polarizing film and transparency paper (for you young folks, that is how we used to “present” things on an overhead projector). I even went so far as to cut the perfect piece of film to fit the HUD screen.
Not surprisingly, it seems as though the actual HUD is a function of the windshield and not what is projected from the small screen in the dash. No matter what orientation I put the film on the screen it didn’t affect what is displayed on the windshield.
