Look in the INSERT META FROM MAP HERE folder, you should see 3 files once you have patched the map.
Before you patched the map you would only have 2, they are both the PNA & META files which will always appear at the bottom of list in the map folder, you copy these over to the INSERT META FROM MAP HERE folder.
Then you go through the patching procedure which will produce that reply you posted.
Now go back into the INSERT META FROM MAP HERE folder and now you have 3 files, the first 2 you copied from the map folder originally and another one ending in .DCT which appeared as you patched the map, copy this .DCT file back into the map folder on your sd card, tomtom etc, that is it fella.
Bit of advice fella, DON'T post your device id on a forum, never know whom's watching
