Can you tell me how to use GPX files on my Tomtom?
Googling would help... Here is what I do:
1. Open your GPS file with the GPX Editor or find the converter link here: https://www.gps-data-team.com/convert.php
2 Select an OV2 file format and press the "SAVE" button
3. Copy the converted OV2 file to your tomtom's map folder on your tomtom.
