Interesting you can surely give it a shot but then you would lose the dual zone when you want it.

or do you think it would default to a single zone until someone messed with the other side.

I doubt it but give it a try. You can always code it back. Let me know!

Have you tried these steps:

3- Press START on the car three times in quick succession
4- start bimmercode app and connect and select BMW for car
5- select BMW Z4 (G29)
6- select Headunit
7- select Expert Mode at top
8- select 3005 DISPLAY_PIP_CONFIG
9- scroll WAY down and select DIM_VARIANT
10- change setting from NEW to OLD 10- click OK.
11- Then backup on screens to the HEADUnit ECU screen.
12- select CODE at top right. Accept risk and let it do its thing.
13- This will enable the Brightness control to be used during Daytime. It will now say Brightness versus Brightness during Nighttime.
14- t will wipe out the 8 hot keys so you will need to remember what you set them to. If the dealer ever does a ECU flash you will have to redo this

What are the Hot Keys?

Im running into an issue with step 10. Unlike videos that I have seen, i do not see a bullet type when selecting old, I have a checkmark instead. There is no "OK" option to click. I am using the full version of Bimmercode.

Does anyone know how to get screen-mirroring option? I don't have the option for it on my car, and I've seen it on other peoples Supras.

I coded the head unit brightness awhile ago as it was way too dim and not visible during the day....I'm still able to control both head unit and cluster display brightness using the thumbwheel control...Coding the headunit had no impact on brightness of the instrument cluster which I found to be sufficiently bright even during the day...

That said, I keep the thumbwheel control at max and never feel the need to change the settings for both day and night driving....

I also have 35% window tint...
Mine went back to dim but the coded change is still set at old, still shows brightness rather than brightness at night, settings at highest level and scroll wheel makes no difference

Along those lines, since Changing Driver Profile can only be done with the car
stopped, can on-the-fly change be coded?
