Installed this on tab 4 and can only get it as far as trying to connect to internet with try again or exit, Any ideas
That's a standard error report when the app can't find your files.
I haven't seen the posters instructions but did you :-
1. Copy the com.tomtom.XXXX folder to your Android/data folder
2. Make a new files folder in the existing files folder.
3. Move the original contents of the original files folder to the new files folder.
4. Move the *.xlm file from the com.tomtom.XXXX folder to your old files folder.
For an unlucky few even doing everything correctly doesn't work, then the games begin.
