W164 Facelift Navigation Upgrade
Okay, so I have a basic NTG-2.5 without the navigation in it, and what I want to do is install the navigation. Since NTG-2.5 navigation is HDD based, can I just add the HDD? If I can, does anyone know what the part number is for the US? If I can't, does anyone know what part number I should be looking to buy for a new COMAND Head Unit? I've been searching the web and cannot find anything to steer me in the right direction.
