Not sure. The owner's manual says you must register it with your mobile carrier, and that the carrier can deny registering it. But it also was stating that if you're directed to stop using it, you have to do so until the dealer uninstalls it because it's an FCC violation or something. So that makes me think it's boost my signal without registration.

Had I known, I would have asked the BMW genius when I did my PCD. In the meantime, I plan to let it ride and not call my carrier about it.

THAT's their fix for polarized glasses???

Well, better than not seeing the HUD I guess.

Wish BMW can figure out a more elegant solution for a $65K car.

I just went with a lot wire from the rear 12v outlet, not super clean but better then using the front one!

What else is there? No pair of polarized glasses are oriented the same. Some may show the display while others not... That's why the option is there. It's not a BMW issue, it's a optical industry issue.

The HUD works by reflecting an image off the windshield, and reflected light will have some degree of polarization. Because you're reflecting vertically off a windshield (similar to the reflection off water), polarized sunglasses will filter out some/most of the HUD image, because polarized sunglasses are made to be effective against light reflected off water.

Until BMW figures out a way to build the HUD display directly into the glass, you're stuck with the hard reality of physics.

(I think the HUD rotation option exists not for sunglasses, but so that BMW doesn't have to do any expensive alignments/calibrations to properly orient the HUD. Otherwise, BMW would have to deal with aligning the HUD during manufacturing, and with possible misalignments caused by jarring bumps during driving.)

Me, I bought new unpolarized (prescription) sunglasses.

In the U.K. the regulations were changed a while ago to make these sort of automotive signal boosters exempt from registration as they are of such low power

The idea of the booster is to give you same signal strength inside car as you would normally have in the same area when outside car rather than massively improve signal

1 feature I miss from my M235i is the ability to set the face vents in the centre of the dash to cool air, there was a hot/cold tub wheel on the M235i

I also think the sound of the doors closing from outside the car isn’t as premium as it should be. Very minor thing but it does t sound premium, not sure if that makes sense.

Upper vent temp can be set from either iDrive, or air conditioning control panel "menu".

Yeah I need to buy a pair of polarized lenses for use outside of the car. Because of the HUD I've had unpolarized ones for years now....I think it's affecting my eyesight. Grrrr...

you sure the HUD rotation option is not meant to let us looking like a puzzled canine while driving, like someone had suggested? :

How would you check that?

Found it thanks much better now I prefer these vents to be cooler.

Also found the ambient lighting setting which I found too bright at night, the dealer had set this to maximum brightness, much better now and less distracting at night.

Bought two nice pair of non polarized sunglasses. One brown, one gray. I leave them in the vehicle. Problem solved.

i think you can also turn on the night driving mode with the Ambient lighting, it dims automatically when driving in the dark. I like this feature and it gives the car a very classy feel.

Yep that was enabled already but too bright due to the setting being on full max.

All sorted

Here is about the only thing I've found not to my liking thus far, three months in on the M40i...who in the hell decided on the REAR wheel well material? OMG, it attracts and retains so much debris I pull my hair out trying to clean them. The front wheel well material is completely different, easy to clean, smooth surface. The rear? It's almost like Velcro.

Maddening. Downright maddening. Why did the materials have to be different, front vs. rear? Any idea?

Sound deadening most likely. This is becoming the standard... My 4 new Dodges had it starting from 2015, noticed a few other MFR's doing it as well...

It also performs a spray suppression role in heavy rain.

Same here. On a related note, it's extremely difficult to find non-polarized lenses these days. However, I was able to get a nice pair of RayBan Aviators NP via Amazon -- still sitting around from the days when everything wasn't polarized. Was a little nervous not trying them on first, but the fit is great and quality as expected.

Oh very cool, thanks for explaining.

I drove around today wearing polarized glasses and found the HUD was very faded, but turning my head or angling the HUD (confused dog solution) didn't do much to fix it. Good to know though!
