NBT HU update: Any notable feature/functionality difference from I-Step 2015 to 2023?

I have a retrofit NBT HU with an emulator. Updated all my ECUs to 2023 I-step Level, but held off on the HU. Any notable feature/functionality difference from I-Step 2015 to 2023? 2015 is the date-year of the HU's current I-Step.

I have been wondering this myself, currently on a 2017 I-step. I suspect it would be bugfixes only.

Just wondering, because installing 28GB of maps every year with millions of addresses and POIs....and I still have to know the exact order of words (city, state street, etc) to voice dictate something...like in 2008.

I figured BMW has already made some innovative progress by 2023 on how to rewrite the NBT Hu's navigation interface to be able to voice search (without a data plan) by "business name" "near me" by using the GPS and the millions of bytes of BMW map data installed (and just taking up worthless space on the NBT hard drive).

BMW should hire a couple of high school kids to revamp it.

BMW is not going to update software coding for a NBT HU with tech last installed 8 years ago.

In reality, the NBT based on 10/11 year old electronics does not have the memory or processing for more advanced searches/features.

There is a reason why you need to buy the newer map updates for the specific type HU you have installed.
