Hi guys,

Made up my mind to do an NBT EVO retrofit for a 03/15 4-series (with the NBT system).

to keep costs down, I'll search for a used unit online. as some of my online purchases have turned me a bit paranoid, I'm trying to understand if there are any physical differences between the evo id4 and id5/6 units. I understand the id5/id6 have more computing power and different GUIs, but I've read that id4 can also be flashed to look like an id5.

so - in short, how can I tell whether I'm getting a genuine id5 unit - or just a flashed id4? can I determine that from the part no.?

Thanks!
