The best option is to have bench setup for evo so You can make update, FSC and all this stuff.

I did it other way - I used friends F30. I've simply put my evo in his car, edited VO to be as similar as mine's e90, did update and fsc. Later setup all togheter in E90 and did some FDL coding according to CarGrade instructions.

More work was with glueing screen to the frame from CCC than with actuall update and coding HU.

I've done a few codings for E60 NBT retrofit (with cargrade) and coding itself is easy, but the unit must have the latest i-levels (at least 2014) to work fine. Else, you need to update.

The i-levels on my E90 have never been updated.So, it remains an older version.
I’ll update when NBT is retrofitted.

Not car's i-level, but HU NBT software. Some parameters from cargrade coding list does not exist on older software.
Car's i-level doesn't matter.

Sorry, I misunderstood.
I'll make sure of i-level when I buy NBT.

The unit will be installed after processing the dashboard.
However, I'll buy the necessary equipment first of all.
