Sorry, my mistake. It should be called "cphonmlh.dat". And you must delete some other files/folders. I will name these files in a few minutes. Must find the harddrive...
Edit: Here we have these missing files: You need to delete also all arp_*_2000_10_10_f.dat
If you get trouble with your Benelux-poi.dat, use the file from the Benelux-NAV3-map.
