Map Update for BWM M5 since 2014 or 520D 416 M Sport

[centrum]

Dear all,

I've just bought my first BWM ever a 520D 416 from 2014, thus, please bear with me until I'm up to speed. I managed to upgrade the software, register the car to BWM but there's no way for me to find the software I see people referring to with which I could download the map update for the navigation system.

This is my Map Version
Europa
BMW Group
101131.3.117
Road Map EUROPE Next 2014-1

NBT_G13024l

I've noticed some seem to have found a way to update the map with a lifetime license - I believe my map is like that, i.e. requires no subscription but it is completely outdated.

Is there a write up you guys have put together with the process?
What is the latest version anyone was able to deploy and working on a BMW 520d dating 2014?
Any tips and best practices you advice?

Thank you in advance for your kindness and help,
Centrum.
