Hello ive a r class facelift model 2011. Originally it cames with the audio 20 ntg 2.5 (color display and bluetooth integrate). Ive retrofitted a comand aps ntg 2.5 all works good except no indications on the cluster and umi (ipod,usb,jack) doesnt works. I didnt go to the official dealer to code with the star dignosis, do you think that code the comand resolves this two issues??

Thanks in advance.
