Hi guys, i have Mercedes ML 350 W164 2006 and it's bought from USA, so it can't be used in Europe

(different hardware). I'm considering to change it, but i'm not sure is it possible to change it with the command from facelift model (NTG 2.5 i think). I like it more because there is a place for CD and SD card, so i won't need a CD changer. My question is about the possibility of changing COMMANDs from different years. Does the connetcors are the same with the NTG 2.0 ? And if it's possible can you give me some advice of DIY way?
