As I was searching for software to import GPX routes to my old TomTom Rider (2010-ish), I found myself at a loss: none of the software for a Mac seemed to work, and I do not have a Windows machine at my disposal. The solution proved simpler than I thought, and it does not require any additional software. I'll outline the steps below.
- Connect you device to your computer (Mac, Windows) using a USB cable.
- Open the device/drive called 'Internal'.
- Copy your GPX file(s) to the (existing) folder called 'gpx2itn'.
- Disconnect your device from your computer and let it reboot.
- Now, if you plan a new route, and navigate to options and 'load route', you'll see the GPX file you copied.
- Done.
Copy your GPX file(s) to the 'gpx2itn' folder in the root of your TomTom drive (probably called 'INTERNAL').
This is more of a reminder for myself, but if anyone finds this useful, that's even better!
