Dear forumers!
Please tell me somebody, what is the difference between two firmware?
Hnav_EU_K0257_6_D1
Hnav_EU_K0257_6_D2
The original 3G map 'activator' was packaged as an MMI firmware update; It worked by just adding/changing one file of the MMI file system. [Subsequent activators are script files which do more work].
If you applied the original activator, you changed the firmware level from whatever was installed to "HNAV_EU_K0257_6_D2".
Systems with the _D1 level are at K0257_6 and haven't had the original activator applied; systems with _D2 HAVE had the activator applied but MAY NOT BE at level K0257 :cautious:

If you're at version P0072, you only need to download K0206, K0253 & K0257-6.

These are RAR files; you need to use WINRAR to expand them to their folders on a Windows PC.

206 will expand to Folders 1, 2, 3 and Metainfo2.txt
253 will expand to many folders and Metainfo2.txt
257 will expand to many folders and metainfo2.txt

These folder sets are 713MB, 556MB & 867MB; you copy them to a blank SD card formatted as FAT32 and install them one at a time, so they easily fit on any SD card bigger than 1 GB.

You have to install via the Red Engineering Menu; I expect they will take about 15-20 mins for each update.

You don't need the Green Engineering menu to install firmware; if you do need it later, it has to be activated by VCDS or an appropriate script file.
