You can use "TT7_910.9185_VGA black.cab" which is the original install file. Install it in to memory card , Then replace the " navigator.exe" with cracked navigator.exe so it reads the maps.

You need to copy the maps into the root of memory card, although sometimes depending on the machine you might need to have the maps in "My Documents" folder, if thats the case you need to create folder in memory card called " My Documents" and edit registry so phone uses the My Documents in memory card.
If you need more information let me know.

You can use the bluetooth gps in tomtom gps settings.
