Hud

Does the 2012 HUD work with polarized sunglasses? The 2011 did not.
The HUD in my C6 does.

Not well. I have a pair of Maui Jims and it significantly reduces the readout...

Which package was HUD an option with? One of the options I really regret not getting is the cameras on the side view mirrors. No aerial view reverse camera for me. Sigh.

It doesn't work well at all. Just one of the downsides of using polarized sunglasses I guess...

Expect the 2012 HUD to be the same as the 2011.

The HUD technology is based on reflections which is light with a specific orientation of the lightwaves.
Polarizers are designed to filter reflections by cancelling lightwaves with a specific orientation...
(Attentive readers already might sense some potential problem at this point)

So whether a HUD "works" or not with any polarizer is actually a matter of matching orientations of reflections and filter!
With any polarized glasses, tilt your head by 90 degrees, and you'll see quite a difference.
Best bet is to buy a non-polarized pair of sunglasses for the car - incidentally, traditional makers of "pilot" sunglasses offer an entire non-polarized product range for obvious reasons.

The glare protection from a pair of Maui Jims is something I have grown accustomed to, especially with snow and rain. It is odd that GM can develop a HUD that works fine with polarized shades and BMW cannot. BTW from my test drive of an A6, the HUD was compatible.
Pilots are not to wear polarized lenses due to the requirement that they be able to judge elevation based on the reflection.

The HUD is not an option I would pay for but is on a 2012 CPO that I am considering

I have maui jims as well. I have found you can read it on both '13 550 and '12 X5 if you turn brightness all the way up. Although it is still noticeably less intense than optimal

I really like the hud. Especially the new speed limit readout. The new crash warning feature is pretty cool too when it flashes a big red car in the hud.

I have a pair of Maui Jims too, which I love, but the HUD hardly works at all with these glasses.

I too thought that I could do without HUD before taking delivery of my F10 but now that I have it, the cool factor alone tells me that I now cannot do without. It is so awesome!

All of this is absolutely correct, as anyone who has ever used a polarizing filter on a camera knows. They have a rotating dial so you can cancel reflections by adjusting the polarizing direction. So brand makes no difference--only the polarization axis is relevant.

Incidentally I tested this with a pair of Oakleys this morning. I could see absolutely no HUD with the sunglasses worn normally. When I turned them 90 degrees, the display was absolutely normal.

Which makes me think we could probably create a business selling nice sunglasses with the direction of polarization oriented properly for BMW HUD devices. Investors, anyone?

Wonder if the Polaroid orientation is standard in the sunglasses industry or will you find variations? How do you know how the filter is oriented? Very curious!

Since the primary purpose is to eliminate glare from horizontal surfaces (e.g., water or roadways) most sunglasses should be polarized vertically. The catch is that glasses that allow visualization of the HUD will inherently be less effective at reducing this glare. Sadly it's hard to get around the laws of physics.

Sounds like you have a crappy pair of sunglasses since by definition a polarized lens should significantly reduce glare and reflections. Which happens to be exactly what the HUD is. This can be verified by the dozen or so people on here who say their MJ's make the HUD hard to read. And let's face it- Maui Jim is one of the best sunglasses manufacturers out there, if not the best...

I'll email Prada about their PR 54is or it's just my 20/20 vision

Then their prices should be reflective of the best no?

I'm heading out to CVS to see if they'll let me swap it for a different pair I think they're having twofer right now!

Prada doesn't make sunglasses, they just put their name on them and charge accordingly. They are there for name only, not to be the best performers...

From Wikipedia -
Visible light waves from the sun travel in all directions. When this scattered light meets a horizontal surface, like a road or water, a large portion of the light is reflected with horizontal polarization. This horizontally-polarized light is seen as white glare, and masks light that is useful to the human eye, reducing visibility. By using a sheet of vertical polarizing material, the horizontally-polarized component can be significantly attenuated, reducing the overall light level reaching the eye. This improves contrast, and thus perception of the scene.
[edit]

COOL! Learned something today, didn't know that light gets aligned in the horizontal plane from reflection from a horizontal surface which means as stated above the filter slots of Polaroid are aligned vertically.

So if HUD get polarized properly there should be not loss of brightness.

I'm certain that the BMW engineers will take this up on Monday and will find a way to make BMW glasses that work with the new, 2015 Polorized HUD!

Its Not standard.
