I had to replace my 2.5 D Command unit from my W220 S class year 2000, i bought one from ebay that had exactly the same codes as my old one but came from a CL, i started to install it and everything went well untill the last connection which is i beleive the sat nav cable wouldnt fit, it has a different end. It looks like the new units end had a ring of metal around the entrance which is preventing me pushing my lead in to it, does any one know a way out for me, everything else works, even the sat nav but obviuolsy not directions or current position ???

Can you send a picture of the connector you have and the back of the comand where the antenna goes to this address; sales@comandonline.co.uk One of the guys there will then advise which converter lead you need.
