2015 BMW i3 Firmware Update

Just noticed my 2015 BMW i3 has a firmware update available on BMW's website:
https://www.bmw.com/update

Looks like it's from December 2018

The list of changes shows: "Improves ConnectedDrive Services."

I'm a little concerned about losing my lifetime maps updates


Interestingly, for the geeks out there... extracting the update archive on my computer shows the BMW i3 is running Linux on ARM:

$ file ./media/bin/bullet
./media/bin/bullet: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 3.1.10, BuildID[sha1]=a33daa264acf14e7bb4b47666e207ff60496d497, stripped

This is a guess based on previous experience, but may not be the case with the latest...that series of updates applies to the phone and built-in cellular stuff, not related to other car functions. IOW, stuff like BlueTooth integration is included, along with various phone compatibility issues.

The documentation read - Improves ConnectedDrive Services.

No other details mentioned, below is the full text.
