Upgrade the Navigation Map Data for NBT Head Units

BMW NBT head units use the map data type of "Next". This can be confirmed by viewing current map type in the CIC screen. Select Navigation, Options, and scroll to the end of the list and select "Navigation system version".

Acquire the E-Sys software and ENET cable for connection to the OBD2 port on the vehicle.

Use the E-Sys software to download the DE file from the vehicle. Save the file, eg DE.fsc.

Acquire the latest map data, eg Road Map NORTH AMERICA Next 2017-2. Determine the AppID and UpgradeID of the map data. Locate the file named Info_Map.imp in the upgrade media. Identify the AppID and UpgradeID.

Generate the FSC code.

Insert the USB media in the vehicle USB port and follow the onscreen upgrade prompt. The directory structure of the NBT navigation USB Media is used as it, without the need to move folders to the root.
