Not that bad but I have it at the right anlge. But what I get a really noticeable purple blotch reflecting onto the inside of the windshield almost all the time there is sun. I think this may be related to the Xpel coating I have on the window as the blotch is always a purplish color. I thought cleaning the HUD area would help but it didn't, wasn't a smudge there causing it as I had thought.
