Linguatronic Full-word entry in Switzerland

Hello colleagues, I’m new here and I have the following question (… and so far I haven’t found a clear answer): I live in Switzerland and I got a SL350 (R230, 2009, Mopf II). As it turns out, this is a vehicle originally sold/approved in DE, which Linguatronic has installed in the Comand. Therefore, the entire electronics in the vehicle is set to DE (according to MB there is some country code for the whole vehicle. g applies…). Problem: Town & street names can currently only be entered for German destinations in full word entry (i.e. without having to spell everything). Although the system language of the command is set to German, and we also speak this language here. If I now choose the country “Switzerland” when entering a destination, Comand tells me with “whole word entry not possible”! Can someone tell me why this is so and how I use the whole word entry additionally (or alternatively) for Switzerland? I assume that the digital data for a Swiss full-word entry is already available on the system (or at least can be played with a card update). I have contacted several MB garages here, but unfortunately so far unsuccessful – no one could help me without having to raise money for an “try” without a guarantee of success. I was assured, however, that with new vehicles sold in Switzerland, a whole-word so at least the digital data on (newer?) card DVDs should be available. Thanks for the help, Christoph
