:-)) we nearly there

Its third way to solve this problem
so missing the post code for UK
use navcore u already downloaded NAVCORE_8.391_TRUCK_SE_GO_910
use map for truck 840.xxx
meta (make sure in side the meta file is this name Europe_TRUCK_2GB_840_2554)
crack them like evrey map
run
download this folder with post codes
Code:
 http://rapidshare.com/files/368527919/post_codes_840.rar
unrar dat
folder ''zip'' put on device, beside map folder (don't change zip name)
let me know

if still not we'll try other way;]

P S old navcore will NOT work with new map, that's way u couldn't run them
