Create a route in above Google Maps window driving directions (get directions) (Note:TomTom itn files can be only 48 points long)
The following is VERRY IMPORTANT
Zoom into the START point as much as possible and move the starting point a few metres. You can even put it back.
Do the SAME for the END point.
Now copy the link location URL from above GoogleMaps window ( Link to this page) into the area below and click the button.
This will make an tomtom *.itn file that you must copy or move to your TomTom device. in the /itn directory
