Doesn’t the Luxury have the facility to make the panoramic roof opaque ?

I think the originally released update has been ‘improved by the IT experts’ and it is trashing the HUD. My concern is that it works very well in my car so I have to guard against the dealer (or maybe an OTA) update winding it back !

Does the 2023 Premium have the HUD ? Here in the UK it doesn’t. Lexus IT fiddled with the update after it was first issued and it crashed all the HUD’s. It was so bad that the affected cars had to have the whole dash removed to replace the HUD - guaranteed to bring creaks and groans. It took Lexus months to sort the problem, but I believe it was sorted.
My May 2023 car was one of the first to have it and it installed well and hasn’t created any problems.
I‘m suggesting this as you said it was a 2023 model - the initial version of the update came in the UK in Feb 24 and all 2024 cars came with it installed.

In the UK, the bz’s had the update months before the RZ. it looks like the bz doesn’t have the HUD so that seems to confirm the issue is to do with the HUD

As seems to be normal in the IT world, they must have tinkered with the original version of the range update. My car has had it and the HUD and everything is fine since. The update was months ago, hence why I think they must have fairly recently tinkered with it.
