I own a W221 2006 that was imported from Japan. The navi does not except to dowload Europe map DVD, the watch is not possible to set correctly, the FM scale stops at 90 Mhz. There are no Connections in the glovebox, and the Bluetooth Works only for the phone. (Iphone, no music) Is it possible to buy a Europe Map that can be installed With the JP NTG3 ? If not, is it a plug and play job, to replace the JP comand With a European Becker NTG3 comand ? (Connections the same). If replaced With the Europe Version, is it possible to add DAB+ in some way ?
