This is a kit to convert an existing UHI or MHI (option 386 / 388) phone system in a W211 E class to the new NTG2.5 Comfort Phone system in cars which have had Comfort Phone retrofitted.

It uses all Genuine Mercedes Parts, and installation involves removing the top tray in the centre armrest, and installing the new upright phone connector at the rear, wiring connections have to be made to the COMAND, and to power and ground.
