Open ITN File

The TomTom Navigator GPS software uses ITN extension files as travel itinerary to save travel routes and POIs as an ASCII text file.

The interesting thing about this application is that it marks the locations as a waypoint or destination points and marks them as visited or not visited.

An important aspect are the fields contained in the ITN extension files, which basically consist of the coordinates of the point, latitude and longitude, in WGS84 format.

As expected, these files can also be transferred to and from a TomTom GPS device via the USB cable.

To open ITN files, you must have one of the following software installed on your system:
