To use any copied Tomtom map, make sure you have a suitable version of the navcore and the correct map version to work with that navcore. The Navcore (ttsystem file) must be patched and then the map must be activated. There are guides and activation tools posted in here to do this for you.

If you still have problems, when asking for any help providing the following information along with any details of what you have tried to do will help to get you going :-

What model of Tomtom ?
What version of Navcore ?
What map & version number ?
Has navcore been patched ?
Has map been activated ?
What activation tools have you tried ?
Have you got the latest me ta file, or have you edited your me ta file (use notepad) with the correct me ta for the map you want to activate ?

any new guides will be in the sticky threads , like this one
