Good evening all. I'm looking at a 2004 ML with COMAND 2.0 and a CD changer, with Option 354 - ANTENNA FOR TELEPHONE D/E-NET, but not Option 386 - Mobile Pre INSTALLATION (MTUS) on the datacard. However, it has a grey square connection in an OE mounting below the glove box, which I understand is for a phone connection; I presume this was fitted at a later date. Does anyone know, is it possible to rig it up for Bluetooth using an adaptor, and will the ancient COMAND unit support it?
