To update the navigation on the NTG55 GU, we first need to download the maps themselves using the official program Mercedes Comand Map Download Manager, then enter a special PIN code for start of update.

In some cases, there are problems when updating to NTG55 and in such cases you may need 2 codes. If we get any errors during the update, then we will need another code, this time to delete old cards! After removing the old cards, everything will be inserted normally.
